我希望用户能够点按一个按钮并进行其他活动。我之前在另一个应用程序中使用过类似的代码,但每次按下按钮,应用程序都会崩溃。在主菜单中我有:
Button testButton = (Button) findViewById(R.id.testButton);
testButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
startActivity(new Intent("de.vogella.android.c2dm.simpleclient.TEST"));
}
});
在清单中:
<activity
android:name=".TestClass"
android:label="@string/app_name" >
<intent-filter>
<action android:name="de.vogella.android.c2dm.simpleclient.TEST" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
TestClass.java是:
package de.vogella.android.c2dm.simpleclient;
import android.app.Activity;
import android.os.Bundle;
public class TestClass extends Activity {
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
}

试试这个:在onClick上修改你的第一堂课:
Button testButton = (Button) findViewById(R.id.testButton);
testButton.setOnClickListener(new View.OnClickListener() {
final ClassName changeAct = this;
public void onClick(View v) {
// TODO Auto-generated method stub
Intent i = new Intent();
i.setClass(changeAct, TEST.class); //Change TEST.class to the name of the class you want it to go to.
startActivity(i);
stop();
}
});

Intent intent = new Intent (CurrentActivity.this, TestClass.class);
startActivity(intent);
如果你的TestClass在另一个软件包中,只需将你的软件包放在前面。
Intent intent = new Intent (CurrentActivity.this, de.vogella.android.c2dm.simpleclient.TestClass.class);
startActivity(intent);
在清单中声明活动,如下所示:
<activity
android:name="de.vogella.android.c2dm.simpleclient.TestClass"
</activity>
