我想按一个按钮,然后显示新的布局。
我做错了什么?
我的类名是:StarWars.java和Test1.java 布局名称:activity_star_wars-.xml和test1.xml
我的代码:
package de.starwars;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_star_wars);
Button jm = (Button) findViewById(R.id.btxJediMaster);
jm.setOnClickListener(new View.OnClickListener()
{
@Override
public void onClick(View v)
{
// TODO Auto-generated method stub
Intent i = new Intent (StarWars.this,Test1.class);
startActivity(i);
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_star_wars, menu);
return true;
}
}
清单:
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="18" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="de.starwars.MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
答案 0 :(得分:0)
替换它:
jm = (Button) findViewById(R.id.btxJediMaster);
jm.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Intent activityChangeIntent = new Intent(StarWars.this,Test1.class);
StarWars.this.startActivity(activityChangeIntent);
}
});
和manifest
:
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="18" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="de.starwars.MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="de.starwars.Test1"/>
</application>
