我设置了启动 Activity ,几秒钟后开始另一个 Activity 。无论如何,我想再添加一项功能:不仅在 5 秒后启动第二个 Activity ,而且在单击启动 View 后启动第二个 Activity。 一旦我设置了下一个:
View v = (View)findViewById(R.layout.splash);
v.setOnClickListener(this);
setContentView(v);
代替
setContentView(R.layout.splash);
我的项目没有运行。 问题出在哪里?
这是我的代码:
public class SlashC extends Activity implements Runnable, OnClickListener {
Thread timer;
MediaPlayer hTree;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
View v = (View)findViewById(R.layout.splash); // problems start here
v.setOnClickListener(this);
setContentView(v);
hTree = MediaPlayer.create(this, R.raw.happy_tree);
hTree.start();
timer = new Thread(this);
timer.start();
}
public void onClick(View v) {
// TODO Auto-generated method stub
Intent class2 = new Intent("com.roger.calc.MainActivity");
startActivity(class2);
}
public void run() {
// TODO Auto-generated method stub
try {
timer.sleep(5000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}finally{
Intent class2 = new Intent("com.roger.calc.MainActivity");
startActivity(class2);
}
}
@Override
protected void onPause() {
// TODO Auto-generated method stub
super.onPause();
hTree.release();
finish();
}}
和 XML
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="@drawable/splash2"
android:clickable="true" >
</LinearLayout>
最佳答案
通过设置布局属性 android:clickable="true"
、android:focusable="true"
和 android:focusableInTouchMode="true"使 LinearLayout 可点击"
来自 xml 或 setClickable(true)
来自代码。将 onClickListener 设置为
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/splash"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:focusableInTouchMode="true"
android:clickable="true"
android:focusable="true"
android:orientation="vertical"
android:background="@drawable/splash2"/>
在代码部分:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
((LinearLayout)findViewById(R.id.splash)).setOnClickListener(this);
