嗨,我想在 prefrencescreen 中添加一个按钮,我成功地将一个按钮添加到 prefrence 中,但我无法获得 onClick 事件。我已经附上了我的代码一张偏好屏幕的图片
设置.xml
<PreferenceCategory android:title="Application Details">
<Preference android:key="type"
android:title="Type"
android:summary="" />
</PreferenceCategory>
<PreferenceCategory android:title="Notification Settings">
<ListPreference android:key="sendNotificationType"
android:title="Status Notification For"
android:dialogTitle="Status Notification For" />
</PreferenceCategory>
设置细节.xml
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_alignRight="@+id/textView2"
android:layout_marginLeft="15dp"
android:text="Type"
android:textAppearance="?android:attr/textAppearanceLarge" />
<TextView
android:id="@+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="@+id/textView1"
android:layout_marginLeft="15dp"
android:layout_toLeftOf="@+id/setFromTimeBtn"
android:text="Summary"
android:textAppearance="?android:attr/textAppearanceSmall" />
<Button
android:id="@+id/buyItNowBtn"
android:layout_width="80dp"
android:layout_height="30dp"
android:layout_alignParentRight="true"
android:layout_marginRight="15dp"
android:layout_centerVertical="true"
android:background="@drawable/button"
android:text="@string/buyItNowBtnTxt"
android:textColor="@color/white" />
以及 prefenceActivity 类的 onCreate 方法
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.layout.setting);
setContentView(R.layout.settingview);
Preference typePref = (Preference) findPreference("type");
typePref.setLayoutResource(R.layout.settingdetail);
typePref.setSelectable(true);
Button btn = (Button) findViewById(R.id.buyItNowBtn);
btn.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
// TODO Auto-generated method stub
Log.e(TAG,"TEST");
Toast.makeText(Setting.this, "TEST", Toast.LENGTH_SHORT).show();
}
});
}
