I've developed an app with gestures in Android.
It simply have four different gestures. Up, down, left and right.
Left and right works well, but up and down is never recognized. It also directly gets uncertain (I set the color to red so I can debug a faster way).
Here's my controller code:
import java.util.ArrayList;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.gesture.Gesture;
import android.gesture.GestureLibraries;
import android.gesture.GestureLibrary;
import android.gesture.GestureOverlayView;
import android.gesture.GestureOverlayView.OnGesturePerformedListener;
import android.gesture.Prediction;
import android.graphics.Color;
import android.util.Log;
import android.view.Menu;
import android.view.View;
import android.view.Window;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;
public class PreperationActivity extends Activity implements OnGesturePerformedListener {
private GestureLibrary gestureLib;
private ImageView ivProfileImage;
private TextView list1, list2, list3, list4;
private TextView tvUsername;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
GestureOverlayView gestureOverlayView = new GestureOverlayView(this);
View inflate = getLayoutInflater().inflate(R.layout.activity_preperation, null);
gestureOverlayView.addView(inflate);
// gestureOverlayView.setGestureVisible(false);
gestureOverlayView.setGestureColor(Color.BLACK);
gestureOverlayView.setUncertainGestureColor(Color.RED);
gestureOverlayView.addOnGesturePerformedListener(this);
gestureLib = GestureLibraries.fromRawResource(this, R.raw.gestures);
if (!gestureLib.load()) {
finish();
}
setContentView(gestureOverlayView);
ivProfileImage = (ImageView) findViewById(R.id.ivProfileImage);
ivProfileImage.setImageBitmap(ListActivity.friends.peek().profileImage);
Intent intent = getIntent();
list1 = (TextView) findViewById(R.id.list1);
list2 = (TextView) findViewById(R.id.list2);
list3 = (TextView) findViewById(R.id.list3);
list4 = (TextView) findViewById(R.id.list4);
list1.setText(intent.getStringExtra("list1"));
list2.setText(intent.getStringExtra("list2"));
list3.setText(intent.getStringExtra("list3"));
list4.setText(intent.getStringExtra("list4"));
tvUsername = (TextView) findViewById(R.id.tvUsername);
tvUsername.setText(ListActivity.friends.peek().username);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.preperation, menu);
return true;
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Session.getActiveSession().onActivityResult(this, requestCode, resultCode, data);
}
#Override
public void onGesturePerformed(GestureOverlayView overlay, Gesture gesture) {
ArrayList<Prediction> predictions = gestureLib.recognize(gesture);
for (Prediction prediction : predictions) {
Log.i("ced", "PREDICTION: " + prediction.score);
if (prediction.score > 1.0) {
Friend friend =ListActivity.friends.pop();
ivProfileImage.setImageBitmap(friend.profileImage);
tvUsername.setText(friend.username);
Toast.makeText(getBaseContext(), prediction.name, Toast.LENGTH_SHORT).show();
}
}
}
}
And my view:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"

android:layout_height="fill_parent"
android:layout_gravity="left"
android:background="#color/list_area_background"
android:gravity="center"
android:text=""
android:textAlignment="center" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
android:gravity="center"
android:orientation="vertical" >
<ImageView
android:id="#+id/ivProfileImage"
android:layout_width="183dp"
android:layout_height="183dp"
android:src="#drawable/com_facebook_profile_picture_blank_square" />
<TextView
android:id="#+id/tvUsername"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Medium Text"
android:textColor="#ffffff"
android:layout_marginTop="5pt"
android:textAppearance="?android:attr/textAppearanceMedium" />
</LinearLayout>
R is just to see if it works and yes, it does.
Any ideas? Thank you!
Have u called this method : addOnGesturePerformedListener ?
I runned the legacy demo then I found that OnGesturePerformedListener causes single up&down gesture not be recognized.

Here is the listview I am sending to my Adapter
listView = (ListView) findViewById(R.id.product_list);
mAdapter = new all_product_list_ArrayAdapter(all_product.this,data);
listView.setAdapter(mAdapter);
Here is my ArrayAdapter Class :

Set your ListView's divider to null and its Divider Height to 0 pixels:
listView = (ListView) findViewById(R.id.product_list);
listView.setDivider(null);
listView.setDividerHeight(0);
mAdapter = new all_product_list_ArrayAdapter(all_product.this,data);
listView.setAdapter(mAdapter);
more info can be found in the docs for ListView here :
ListView#setDivider(android.graphics.drawable.Drawable)
ListView#setDividerHeight(int)
use divider for ListView in this way:
<ListView
android:id="#+id/list"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:divider="#null"
android:dividerHeight="0dp"/>
I have a button at the end of this app that takes the user to their default browser and to a predetermined link. Unfortunately, that button is broken. I am unsure of whether this is a problem with Java or with XML, but the code for both is attached.
package com.example.ldsm3;
import android.net.Uri;
import android.os.Bundle;
import android.app.Activity
import android.content.DialogInterface;
import android.content.Intent;
import android.text.SpannableString;
import android.text.method.LinkMovementMethod;
import android.text.method.MovementMethod;
import android.view.Menu;
import android.widget.Button;
import android.widget.TextView;
public class Finished extends Activity {
public void onClick(Button button1)
{
Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("URL HERE"));
startActivity(browserIntent);
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_finished);
// tv is the ID for the TextView in the XML file
TextView tv = (TextView) findViewById(R.id.textView2);
// set the TextView to show the score
tv.setText(Misc.correct + "/" + Misc.total);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.finished, menu);
return true;
}
}
And the XML code...
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context=".Finished" >
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="69dp"
android:text="#string/Finished" />
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignRight="#+id/textView1"
android:layout_marginBottom="19dp"
android:text="Go to the game!" />
<TextView
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="#+id/button1"
android:layout_centerHorizontal="true"
android:layout_marginBottom="93dp"
android:text="0/0" />
</RelativeLayout>
How do I fix this? Is it because of XML or Java? Did I not properly define the intent?
You need to add this on your onCreate() method:
Button button1 = (Button) findViewById(R.id.button1);
button1.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v) {
//Do your stuff here
}
});
Hi I have an m file which is a relative layout and which contains 9 image buttons.
So I would like to reuse my layout multiple times just by changing the names and ID's.
I am able to do with gridview but my problem is I want use the same customs design which I have using relative layout.
So can any one help how to do it.

I have written my activity java it itself creates the image buttons in a gridview. But I use like this I want to use in such way that I call my customs layout in different activities because the layout is same only the IDs and some images will change.
If I understand it right - you have a custom design layout with buttons and you want to use this same layout in other screen as well.
You don't need to rename anything, just put the layout in a separate xml, let's say CommonButtonLayout.xml. This should contain like this:
<?xml version="1.0" encoding="utf-8"?>
<merge xmlns:android="http://schemas.android.com/apk/res/android" >
.... your layout .....
</merge>
Now you want to use this in other layout files. You need to include this xml directly there like the following.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
...
...
>
<include
android:layout_centerVertical="true"
layout="#layout/CommonButtonLayout" />

I have one button on First Activity xml layout .The first Activity Layout display after run application but whenever i click on button on first xml first want to go on next laytout after clicking then this error show in LogCat tab and application stop working.
AndroidRuntime at dalvik.system.NativeStart.main(Native Method)
what i should do?
The right way to do this given below:
next.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
Intent nextScreen = new Intent(MainActivity.this, CopyOfMainActivity.class);
startActivity(nextScreen);
//finish();
}
} );
Hope this will work fine.
Please add your both activities to Manifest file if you missed out.
<application>
<activity android:name="Activity1">
</activity>
<activity android:name="Activity2">
</activity>
public void butt591(View v) {
v.startAnimation(fivenineclick);
Button but591 = (Button) findViewById(R.id.button591);
but591.setBackgroundColor(Color.parseColor("#ee4035"));
Intent bu591 = new Intent();
bu591.setClass(this, level5q10.class);
startActivity(bu591);
finish();
}
hey, i copy pasted a part of code in my app here 591 denotes level 5 ninth question and on selecting first option
that is wrong answer so on clicking the option it will set background to #ee4035 which is red color and when the user presses this option it will switch to level 5q10
I hope you understood from this code
I have an activity that is works fine and displays data obtained from a table query. With an OnItemClick method, I have it set up so that if a row is selected, a new activity starts with a new ListView, but a lot of the elements from the original ListView are in the new listview, including a toggle button on each row, and a text view. Any idea what could be causing this?
This is the initial ListView. The buttons don't show up, just everything in the ListView:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#81BEF7"
android:orientation="vertical" >
<Button
android:id="#+id/btnAddNurseToRoster"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/add"
android:focusable="true"/>
<Button
android:id="#+id/btnRemoveNurseFromRoster"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignTop="#+id/btnAddNurseToRoster"
android:layout_toRightOf="#+id/btnAddNurseToRoster"
android:text="#string/delete"
android:focusable="true"/>
<ListView
android:id="#+id/android:list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_below="#+id/btnAddNurseToRoster"
android:textColor="#FFFFFF"
android:textStyle="bold"/>
</RelativeLayout>
New ListView:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#81BEF7"
android:orientation="vertical" >
<TextView
android:id="#+id/tvAssignmentsText"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textSize="25dp"
android:textColor="#FFFFFF"
android:text="Assignments"
android:gravity="center_horizontal"
android:background="#663399"
/>
<ListView
android:id="#+id/lvAssignmentsList"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_below="#+id/tvAssignmentsText"
android:paddingTop="20dp"
android:textColor="#FFFFFF"
android:textStyle="bold"/>
</
And here's the code that calls the new ListView:
package com.deadEddie.staffingmanagement;
import android.app.Activity;
import android.database.Cursor;
import android.os.Bundle;
import android.support.v4.widget.SimpleCursorAdapter;
import android.util.Log;
import android.widget.ListAdapter;
import android.widget.ListView;
public class ShowAssignments extends Activity {
DbCommunicator getAssignmentsList;
ListView assignmentsList;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.assignments);
displayList();
}
private void displayList() {
// instantiate ListView object
assignmentsList = (ListView) findViewById(R.id.lvAssignmentsList);
// instantiate variables for CursorAdapter
int [] to = new int [] {R.id.rbAssignmentsList };
String [] from = new String [] {DbCommunicator.KEY_ROOM_NUMBER};
// instantiate getAssignmentsList with new DbCommunicator object and open
getAssignmentsList = new DbCommunicator(this);
getAssignmentsList.open();
// get and manage cursor
Cursor assignmentsCursor = getAssignmentsList.getAssignments(this);
startManagingCursor(assignmentsCursor);
// list adapter
ListAdapter assignmentsListAdapter = new SimpleCursorAdapter(this, R.layout.nurse_list, assignmentsCursor, from, to, 0);
assignmentsCursor.moveToNext();
// set ListView
assignmentsList.setAdapter(assignmentsListAdapter);
assignmentsList.setItemsCanFocus(true);
}
}

listView.setOnItemClickListener(new OnItemClickListener(){

long id) {
Log.i(TAG, "onItemClickListener set");

switch (v.getId())

startActivity(add);
break;
case R.id.btnRemoveNurseFromRoster:
break;
} // switch
}
}
Okay. Got it. Just realized that I mistakenly used the same layout (nurse_list) when I instantiate the ListAdapter in each method so it tried to apply my new data query to the original layout (which was screwed up of course). Thanks for taking a look though, really appreciate it.
Sorry if this wastes anyone's time. Maybe a lesson for other newbies out there.
