我创建了以下自定义首选项屏幕。

我想在 Button1 和 Button2 上添加监听器。我应该怎么做？

我正在使用以下代码创建上述首选项屏幕。

演示首选项:

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;

public class DemoPref extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        startActivity(new Intent(this, MyPref.class));
    }
} 

我的偏好:

import android.os.Bundle;
import android.preference.PreferenceActivity;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class MyPref extends PreferenceActivity{
    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        //setContentView(R.layout.tftp_setting);
        this.addPreferencesFromResource(R.xml.list_pref);
        /*Button b1 = (Button)findViewById(R.id.button1);
        b1.setOnClickListener(new OnClickListener(){

            @Override
            public void onClick(View v) {

                Log.i("MyPref", "Button1 one is clicked.");
            }           
        });

        Button b2 = (Button)findViewById(R.id.button2);
        b2.setOnClickListener(new OnClickListener(){

            @Override
            public void onClick(View v) {

                Log.i("MyPref", "Button2 one is clicked.");
            }           
        });*/
    }
}

资源\布局\设置.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"

    <Button android:text="Button2" android:id="@+id/button2" android:layout_width="wrap_content" android:layout_height="wrap_content"></Button>

   </LinearLayout>
</LinearLayout>

res\xml\pref.xml:

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen

 <PreferenceScreen  android:title="My Setting"  android:layout="@layout/setting" android:summary="This is my setting."></PreferenceScreen>

</PreferenceScreen>

最佳答案

你需要:

Button b1 = (Button) findViewById(R.id.button1);
Button b2 = (Button) findViewById(R.id.button2);

b1.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
        Log.i("MyPref", "Button1 one is clicked.");
    }
});

b2.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
        Log.i("MyPref", "Button2 one is clicked.");
    }
});
