1。自定义字符串
Open “res/values/strings.xml” file, add some custom string for toggle buttons.
res/values/strings.xml文件：
<?xml version="1.0" encoding="utf-8"?><resources> <string name="app_name">MyAndroidApp</string> <string name="toggle_turn_on">Turn On</string> <string name="toggle_turn_off">Turn Off</string> <string name="btn_display">Display</string></resources>
2。切换按钮
Open “res/layout/ main.xml” file, add two “切换按钮” and a normal button, inside the 线性布局.
文件：res/layout/ main.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" android:orientation="vertical" > <ToggleButton android:id="@+id/toggleButton1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="ToggleButton" /> <ToggleButton android:id="@+id/toggleButton2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textOn="@string/toggle_turn_on" android:textOff="@string/toggle_turn_off" android:checked="true" /> <Button android:id="@+id/btnDisplay" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/btn_display" /></LinearLayout>
笔记
Review the “togglebutton2”, we did customized the togglebutton2’s display text on and off and made it checked by default.
三.代码代码
Inside activity “onCreate（）” method, attach a click listeners on a normal button, to display the current state of the toggle button.
文件：myandroidappactivity.java
package com.mkyong.android;import android.app.Activity;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.Toast;import android.widget.ToggleButton;public class MyAndroidAppActivity extends Activity { private ToggleButton toggleButton1, toggleButton2; private Button btnDisplay; @Override
public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState);
setContentView(R.layout.main);
addListenerOnButton();
} public void addListenerOnButton() {
toggleButton1 = (ToggleButton) findViewById(R.id.toggleButton1);
toggleButton2 = (ToggleButton) findViewById(R.id.toggleButton2);
btnDisplay = (Button) findViewById(R.id.btnDisplay);
btnDisplay.setOnClickListener(new OnClickListener() { @Override
public void onClick(View v) {
StringBuffer result = new StringBuffer();
result.append("toggleButton1 : ").append(toggleButton1.getText());
result.append("\ntoggleButton2 : ").append(toggleButton2.getText());
Toast.makeText(MyAndroidAppActivity.this, result.toString(),
Toast.LENGTH_SHORT).show();
}
});
}
