I'm new to Android and I have been struggling to draw on canvas a rectangle and text where the size of the rectangle, the text and the color depend on values selected from a MySql database.
I managed to get data selected inside my Activity, but I just can't figure it out how to pass the MySql data to the ondraw() method so I can draw the rectangle and text using the data.
Any help will be greatly appreciated.
public class MyTankActivity extends AppCompatActivity {
#Override

Response.Listener<String> responseListener = new Response.Listener<String>() {
#Override

One suggestion:
Move JSON data to global variables
public class MyTankActivity extends AppCompatActivity {
String location;
String color;
String Level;
//....
And change setContentView with different constructor of TankView that allows to pass the obtained data:
setContentView(new TankView(this, location, color, Level));
Modify the constructor of TankView accordingly, also add some variables to TankView to store this values:
public TankView(Context context, String loc, String color, String level) {
super(context);
init(null, 0);
this.location = loc;// ... do the same with color/level
...
}
Modify the onDraw after you get the data
#Override
public void onDraw(Canvas canvas) {
super.onDraw(canvas);
//using this.Location, color, text
// canvas.drawText();.
// canvas.rect();
}

I've created a custom XML layout and I’m trying to draw the map background and the pawn player( the bitmap) over it.
Instead, its painting the pawn player over a white background without the map background that I put as the background on the XML file.
MyViev Class:
package com.example.alpha;
import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.Canvas;
import android.util.AttributeSet;
import android.view.View;
public class MyView extends View {
Bitmap playerW;
float changingY;
float changingX;
public MyView(Context context) {
super(context);
playerW = BitmapFactory
.decodeResource(getResources(), R.drawable.black);
changingY=0;
// TODO Auto-generated constructor stub
}
#Override
protected void onDraw(Canvas canvas) {
// TODO Auto-generated method stub
super.onDraw(canvas);
canvas.drawBitmap(playerW,4+changingX, (canvas.getHeight())-288-changingY, null);
}
public MyView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
// TODO Auto-generated constructor stub
}
public MyView(Context context, AttributeSet attrs) {
super(context, attrs);
// TODO Auto-generated constructor stub
}
}
my MainActivity Class:
package com.example.alpha;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
public class MainActivity extends ActionBarActivity {
MyView ourView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ourView = new MyView(this);
setContentView(ourView);
}
}
My XML file:
<?xml version="1.0" encoding="utf-8"?>
<view class="com.example.alpha.MyView"
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/myView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/mapeasy"
/>
It's because you're not actually setting it to use your XML layout. Instead, you've set the content View to be a new instance of MyView, which doesn't have the XML background property set.
Therefor you have 2 options:
Option 1: Call ourView.setBackgroundDrawable(R.drawable.mapeasy); after you created a new instance of MyView.
or
Option 2: Set the content View to be your actual layout file and then find your MyView by using findViewById(int).
Eg.
public class MainActivity extends ActionBarActivity {
MyView ourView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.your_layout_file);
ourView = (MyView)findViewById(R.id.myView);
}
}
My app consist on moving a picture when the user speaks. I have done this, but what I want to do now is that I want to set a image as background for my app. I am working with canvas, as you can see in the class I have included below. So how can I set a background using canvas and not influencing the movement of my picture. Or is there any possibility to connect this class with a xml file where I can define the background?
Thanks in advance

You can use an xml layout instead of setting content view with a java object :
setContentView(R.layout.move_balloon);
and add your custom view (DrawBalloon) in the xml layout by specifying it's package location, and change the background by setting an image to the background of the root element :
<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"
tools:context=".MoveBalloon"
android:background="#drawable/ic_launcher"
>
<com.example.prova1.MoveBalloon.DrawBalloon
android:id="#+id/drawBalloon1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="182dp" />
</RelativeLayout>
but for this to work , your custom view must have a special constructor in able to be inflated from xml layout file :
public DrawBalloon(Context context, AttributeSet attrs) {
super(context, attrs);
ourHolder= getHolder();
}
this here is driving me nuts...
I want to pass some Parameters with a Button Constructor
I did create myButton extending Button:
package com.canbluetoothinterface.utilities;

import android.view.View.OnClickListener;
import android.app.Activity;
import android.content.Context;

import android.widget.Button;
import android.widget.EditText;
public class myActivityStartButton extends Button implements OnClickListener {
protected EditText[] Array;
private String Name;
private String BufferName;
private Activity activityinstance;
public String[] sValues;
Class<?> cls;
private Method m;
public myActivityStartButton(String Name, Class<?>clsin, Context context) {
super(context);
cls = clsin;
activityinstance = (Activity) context;
setId(mygetId());
this.Name = Name;
init();
}
private void init(){
setOnClickListener(this);
}
public myActivityStartButton(String Name, Class<?>clsin, Context context, Method min) {
super(context);
this.cls = clsin;
this.Name = Name;
this.m = min;
activityinstance = (Activity) context;
setId(mygetId());
setTag(findViewById(mygetId()));
init();
}
#Override
public void setId(int id) {
super.setId(id);
}
private int mygetId() {
int id = 0;
BufferName = Name;
id = activityinstance.getResources().getIdentifier(BufferName, "id", activityinstance.getPackageName());
return id;
}
#Override
public void onClick(View v) {
try {
m.invoke(null, (Object)null);
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalAccessException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (InvocationTargetException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Intent intent = new Intent(activityinstance, cls );
activityinstance.startActivity(intent);
}
}
In my Activity I call:
Start = new myActivityStartButton("act_testdriveconfiguration_btn_start", DeviceListActivity.class, this, mstartbutton);
But my OnClick is never called...
What am I doing wrong?
Thank you
1.double check your init() is called.
The following code works for me.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
RelativeLayout layout = (RelativeLayout) findViewById(R.id.main_container);
SomeButton btn = new SomeButton(this);
layout.addView(btn);
}
private class SomeButton extends Button implements OnClickListener {
public SomeButton(Context context) {
super(context);
init();
}
private void init() {
setOnClickListener(this);
}
#Override
public void onClick(View v) {
Log.w("log", "click");
}
}
NOTE:
if your button is created in xml, you need these constructors.
public setParams(String Name, Class<?>clsin,etc params)
{
//saving params
}
public SomeButton(Context context) {
super(context);
init();
}
public SomeButton(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
public SomeButton(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
init();
}
I am trying to overlay a drawing on top of a camera preview. I made two custom class extended from SurfaceView: one for the overlay, and one for the cam.
Here is my logcat (only the "Caused by" statements) :
04-11 19:58:06.549: W/dalvikvm(867): threadid=1: thread exiting with uncaught exception (group=0x40a71930)
04-11 19:58:06.609: E/AndroidRuntime(867): Caused by: android.view.InflateException: Binary XML file line #5: Error inflating class com.example.gui_v9.Activity1.CamView
04-11 19:58:06.609: E/AndroidRuntime(867): Caused by: java.lang.ClassNotFoundException: Didn't find class "com.example.gui_v9.Activity1.CamView" on path: /data/app/com.example.gui_v9-2.apk
The second error where it cannot find the class, is because it did not inflate.
Eclipse Graphical Layout successfully compiles the xml code and gives a decent preview. Here is my XML code:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<com.example.gui_v9.Activity1.CamView
android:id="#+id/camview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
<com.example.gui_v9.Activity1.OverlayView
android:id="#+id/overlay"
android:layout_width="200dp"
android:layout_height="200dp"/>
</FrameLayout>
I tried to change the flags from
<com.example.gui_v9.Activity1.OverlayView .../>
to
<com.example.gui_v9.Activity1.OverlayView ...></com.example.gui_v9.Activity1.OverlayView>
or to
<SurfaceView class="com.example.gui_v9.Activity1$OverlayView" ... />
or even
<SurfaceView class="com.example.gui_v9.Activity1$OverlayView" ... ></SurfaceView>
without luck. In the latter case, I have a casting problem (CamView cannot be casted in SurfaceView) and Eclipse's XML Graphical Layout fails to render, so I m guessing that the first one takes me further in the compiling process.
You may also take a look at my main activity:

As you can see, I have the three constructors for each classes (with 1,2 and 3 arguments) which is a common error in inflating class failure.
I got this to work when I implemented CamView and OverlayView in two separate classes (CamView.java and OverlayView.java), respectively. So I don't understand why importing classes makes it work. Maybe something with the static workspace?
Thank yall for your help!
I am creating a live wallpaper settings activity. It has a few seek bars and an Ad Mob ad view. Every time I touch one of the seek bars the ad temporarily disappears and then reloads a new add. However, the ad does not change when any of the other preferences are touched. How do I stop the ad from reloading when a seek bar preference is touched? I am pretty stumped on this one :-). Code follows:
The ad preference class:
import android.app.Activity;
import android.content.Context;
import android.preference.Preference;
import android.util.AttributeSet;
import android.view.View;
import android.view.ViewGroup;
import android.widget.LinearLayout;

public class AdPreference extends Preference {
public AdPreference(Context context, AttributeSet attrs, int defStyle) {super (context, attrs, defStyle);}
public AdPreference(Context context, AttributeSet attrs) {super(context, attrs);}
public AdPreference(Context context) {super(context);}
#Override
protected View onCreateView(ViewGroup parent) {
// this will create the linear layout defined in ads_layout.xml
View view = super.onCreateView(parent);
// the context is a PreferenceActivity
Activity activity = (Activity)getContext();
// Create the adView
AdView adView = new AdView(activity, AdSize.BANNER, "a151390e12917b5");
((LinearLayout)view).addView(adView);
// Initiate a generic request to load it with an ad
AdRequest request = new AdRequest();
request.addTestDevice("23392C83B8B55DE893A18286CB92DDA2");
request.addTestDevice("E1BAA0317138AEE05268B2E4F76B2D3F");
adView.loadAd(request);
return view;
