This question already has answers here:
how can I create clean Button in AutoCompleteTextView
(3 answers)
Closed 6 years ago.
This is the app that I am developing.
I am using AutoCompleteTextView.
I want to put an X inside it. Can you help me adding that?
Here is my code
MainActivity.class
package com.example.guidemo3;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.AutoCompleteTextView;
import android.widget.TextView;
public class MainActivity extends Activity {
AutoCompleteTextView autocomplete;
String[] stateName = { "France", "Philippines","Brazil",
"Italy", "United States"};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
autocomplete = (AutoCompleteTextView)
findViewById(R.id.autoCompleteTextView1);
ArrayAdapter<String> adapter = new ArrayAdapter<String>
(this,android.R.layout.simple_dropdown_item_1line, stateName);
autocomplete.setThreshold(1);
autocomplete.setAdapter(adapter);
autocomplete.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
String stateName = autocomplete.getAdapter().getItem(position).toString();
// Put selected state to intent.
Intent intent = new Intent(MainActivity.this, NextActivity.class);
intent.putExtra("selectedState", stateName);
startActivity(intent);
}
});
TextView cancelButton = (TextView) findViewById(R.id.cancelButton);
cancelButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
autocomplete.setText("");
}
});
}
}
activity.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
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"
android:focusableInTouchMode="true"
>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/search_view_border"
android:orientation="horizontal">
<AutoCompleteTextView
android:id="#+id/autoCompleteTextView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:ems="20"
android:hint="Search"
android:padding="10dp">
<requestFocus/>
</AutoCompleteTextView>
<TextView
android:id="#+id/cancelButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text=" X "
android:textColor="#000"/>
</LinearLayout>
</RelativeLayout>
You have to put a LinearLayout around your AutoCompleteTextView
Then add your Background to that Layout
Place a TextView with an " X " as Text inside that Layout an add an OnClickListener.
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/search_view_border"
android:orientation="horizontal">
<AutoCompleteTextView
android:id="#+id/autoCompleteTextView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:ems="20"
android:background="#android:color/transparent"
android:hint="Search"
android:padding="10dp">
<requestFocus/>
</AutoCompleteTextView>
<TextView
android:id="#+id/cancelButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text=" X "
android:textColor="#color/colorPrimaryDark"/>
</LinearLayout>
OnClickListener would look like this:
cancelButton = (TextView) findViewById(R.id.cancelButton);
cancelButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
autocomplete.setText("");
}
});

I'm building a Contact app using ListView. My ListView has 2 button. In this app, to test the respond ability of the buttons, I intended to set the button "Edit" so that when I click on it, it will change to "Clicked", and the button "Delete" will change to "Clicked", too. When I ran the Debug, the app stopped working and I couldn't get it work again (before I added the onClickListener, this app had worked property).
I don't know what is the error, and have tried many ways to fix.
Here is my row_listview.xml:
<?xml version="1.0" encoding="utf-8"?>

And here is my MainActivity.java:
package com.huy9515gmail.mycontact;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.LinearLayout;
import android.widget.ListView;
import android.widget.RadioButton;
import android.widget.RadioGroup;
import android.widget.Toast;
import java.util.ArrayList;
import butterknife.BindView;
import butterknife.ButterKnife;
public class MainActivity extends AppCompatActivity {
#BindView(R.id.edt_inputName) EditText edtName;
#BindView(R.id.btnAdd) Button btnAdd;
#BindView(R.id.btnEdit) Button btnEdit;
#BindView(R.id.btnDelete) Button btnDelete;
#BindView(R.id.edt_inputNumber) EditText edtNumber;
#BindView(R.id.rdbtn_male) RadioButton rdbtn_male;
#BindView(R.id.rdbtn_female) RadioButton rdbtn_female;
#BindView(R.id.rdbtn_others) RadioButton rdbtn_others;
#BindView(R.id.gender) RadioGroup genderSelection;
private ListView lvContact;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ButterKnife.bind(this);
lvContact = (ListView) findViewById(R.id.lv_contact);
final ArrayList<Contact> arrContact = new ArrayList<>();
btnAdd.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//validating contact info
if (((edtName.getText().toString().trim()) == "") || (edtNumber.getText().toString().trim() == "") || ((rdbtn_male.isChecked()==false) && (rdbtn_female.isChecked()==false) &&(rdbtn_others.isChecked()==false))) {
Toast.makeText(MainActivity.this, "Invalid contact info! Please try again!", Toast.LENGTH_SHORT).show();
}
//adding contact info
else {
Contact contact = new Contact(Gender.male, "", "");
//adding info
contact.setName(edtName.getText().toString());
contact.setNumber(edtNumber.getText().toString());
arrContact.add(contact);
}
CustomAdapter customAdapter = new CustomAdapter(MainActivity.this, R.layout.row_listview, arrContact);
lvContact.setAdapter(customAdapter);
}
});
}
public void myClickHandler(View v) {
LinearLayout vwParentRow = (LinearLayout) v.getParent();
Button btnEdit = (Button) vwParentRow.getChildAt(0);
Button btnDelete = (Button) vwParentRow.getChildAt(1);
btnEdit.setText("Clicked");
btnDelete.setText("Clicked");
}
}
And here is the row_listview.xml layout:
Instead of setting the android:onClick in XML, do the same as you did for btnAdd.
Find the view by id or use butterknife, then put the following in onCreate()
btnEdit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Your code here
}
});
btnDelete.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Your code here
}
});
Make sure you have an element in your XML file with the id like this:
android:id="#+id/btnAdd"
When trying to run our app, we consistently have errors with conflicting fragments not letting us run the activity. Here's a screencast of the problem I am facing
As you can see, the app itself contains a multitude of problems, but my primary focus is getting the clicker to respond on the click. Here is the class page for the clicker activity:
package com.example.android.Chapsnat;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
public class ContactsFragment extends AppCompatActivity {
Button btnClick;
Button btnReset;
TextView txtCount;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fragment_contacts);
btnClick = (Button)findViewById(R.id.buttonClick);
btnReset = (Button)findViewById(R.id.buttonReset);
txtCount = (TextView)findViewById(R.id.textViewCount);
btnClick.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
String countValue = txtCount.getText().toString();
int intCountValue = Integer.parseInt(countValue);
intCountValue++;
txtCount.setText(String.valueOf(intCountValue));
} });
btnReset.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
txtCount.setText(String.valueOf(0));
}
});
}
}
And this is the xml page it is being built in, which is also a fragment:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"

android:layout_marginTop="66dp"
android:text="0"
android:textColor="#android:color/holo_purple"
android:textSize="40sp" />
<Button
android:text="Click"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/buttonClick"
android:layout_below="#+id/textViewCount"
android:layout_centerHorizontal="true"
android:layout_marginTop="79dp" />
<Button

android:layout_marginTop="171dp"
android:id="#+id/buttonReset"
android:layout_below="#+id/textViewCount"
android:layout_alignStart="#+id/buttonClick" />
</RelativeLayout>
Is there any way you can help? If so please let me know.
I have an image file on which if clicked anywhere I would like X'd checkboxes to show up. (Right now its set up as check marks). The code that I have is just for connecting page 1 to page 2 with a button click. Here it is
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
public class MainActivity extends AppCompatActivity {
public static Button button1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
OnclickButtonListener();
}
public void OnclickButtonListener() {
button1 = (Button) findViewById(R.id.nextpage);
button1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
EditText userTextEntry = (EditText)findViewById(R.id.BRinfo);
String userdata = userTextEntry.getText().toString();
int userNumber = Integer.parseInt(userdata);
Intent intent = new Intent(MainActivity.this,Page2.class);
intent.putExtra("para name",userNumber);
startActivity(intent);
}
});

I want the value of textbox to display on the same screen(scrollview)box and also i want to pass a httppost request to pass a value..plz help me out
Thnks in advance
I think, you can use a ListView insted of scroll view. and add list items from the chat text value dynamically.
call notifydatasetchanged() every time when you add a new item to it.
<TextView
android:id="#+id/username"
android:layout_width="match_parent"
android:layout_height="50dp"
android:gravity="center_vertical"
android:layout_alignParentTop="true"
android:textColor="#000000"
android:text="aakash"
android:background="#c0c0c0"
/>
<ListView
android:id="#+id/listView_chats"
android:layout_width="match_parent"
android:layout_height="100dp"
>
</ListView>
<EditText
android:id="#+id/chattxt"
android:layout_width="230dp"
android:layout_height="45dp"
android:hint="type here"
android:inputType="textMultiLine" />
<Button
android:id="#+id/sendbtn"
android:layout_width="75dp"
android:layout_height="45dp"
android:text="Send" />
</LinearLayout>
Write a custom adapter for the listView and add the code to manage the list data.

Simply I want to create a basic shopping app that have 20 products. the price and product name will come from server and quantity will input by user so how do I that?
You are looking for something like this
int count = container.getChildCount();
for (int i = 0; i < count; i++) {
final View row = container.getChildAt(i);
TextView textOut = (TextView)row.findViewById(R.id.textout);
String data = textOut.getText().toString();
}
Where container is your LinearLayout in which you have added your inflated rows.
Try this:-
To take user input from text box:-
int qty = Integer.parseInt(qtyTextBox.getText().toString());
Caluculate bill:-
double bill = price*qty;
Send bill value to next activity:-
Intent in = new Intent();
in.putExtra("Bill", bill);
startActivity(in);
Get bill value in next activity:-
Intent in = getIntent();
int mBill = in.getExtra("Bill");
string bill = String.valueOf(mBill);
Now you can set the value of 'bill' to the TextView where you want to display it.
