我有一个文本阅读器应用程序,旨在当我单击文本文件打开它时接收来自 Android 系统的意图。但我的应用不在系统弹出的列表中。以下是我的代码:
显现
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.broadcastreceivertest1"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="8" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >
<activity
android:label="@string/app_name"
android:name=".BroadcastReceiverTest1Activity" >
<intent-filter >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:name="MyBroadcastReceiver">
<intent-filter>
<action android:name="android.intent.action.ACTION_VIEW" />
<action android:name="android.intent.action.ACTION_EDIT" />
<action android:name="android.intent.action.ACTION_PICK" />
<data android:scheme="file" />
<data android:mimeType="*/*" />
<data android:pathPattern=".*\\.txt" />
<data android:host="*" />
</intent-filter>
</receiver>
</application>
</manifest>
我的扩展广播接收器
public final class MyBroadcastReceiver extends BroadcastReceiver {
private String TAG = "MyBroadcastReceiver";
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
Intent i = new Intent(context, BroadcastReceiverTest1Activity.class);
i.putExtra("URI", intent.getData());
context.startActivity(i);
Log.d(TAG, "Leaving onReceived...");
}
}
我的活动将由广播接收器打开
public class BroadcastReceiverTest1Activity extends Activity {
private String uri ="";
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final Intent intent = getIntent();
final String action = intent.getAction();
if(Intent.ACTION_VIEW.equals(action)){
uri = intent.getStringExtra("URI");
TextView textView = (TextView)findViewById(R.id.textView);
textView.setText(uri);
}
}
}
谢谢!
