Хорошо, я работаю над проектом и пытаюсь использовать кнопки с текстом внутри них в упражнении, но затмение не может найти идентификатор или chooser.xml
Вот класс myActivity
package com.xxxxxxx;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.widget.Button;
import android.widget.ImageButton;
import android.view.*;
public class MyActivity extends Activity {`
private Button mButton1;
private Button mButton2;
private Button mButton3;
private Button mButton4;
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
//chooser is underlined (chooser cannot be resolved or is not a field)
setContentView(R.layout.chooser);
//all ids are underlined(id cannot be resolved or is not a field)
mButton1 = (Button) findViewById(R.id.button1);
mButton2 = (Button) findViewById(R.id.button2);
mButton3 = (Button) findViewById(R.id.button3);
mButton4 = (Button) findViewById(R.id.button4);
mButton1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent myIntent = new Intent(MyActivity.this, Activity2.class);
startActivity(myIntent);
}
});
mButton2.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent myIntent = new Intent(MyActivity.this, Activty3.class);
startActivity(myIntent);
}
});
mButton3.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent myIntent = new Intent(MyActivity.this, Activity4.class);
startActivity(myIntent);
}
});
mButton4.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent myIntent = new Intent(MyActivity.this, Activity5.class);
startActivity(myIntent);
}
});
}
}
Вот файл chooser.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<Button
android:id="@+id/button_1"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="@string/button_1" />
<Button
android:text="@string/button_2"
android:id="@+id/button_2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<Button
android:id="@+id/button_3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/button_3"
/>
<Button
android:id="@+id/button_4"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="@string/button_4"
/>
</LinearLayout>
А вот строковый ресурс xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="app_name">Test App</string>
<string name="test_image">test.png</string>
<string name="button_1">button_1</string>
<string name="button_2">button_2</string>
<string name="button_3">button_3</string>
<string name="button_4">button_4</string>
</resources>
