Android--创建快捷方式

manifest 中添加权限:

"com.android.launcher.permission.READ_SETTINGS"/>

"com.android.launcher.permission.INSTALL_SHORTCUT"/>

在点击快捷方式对应的那个activity添加属性:

 

    "android.intent.action.MAIN" />
    "android.intent.category.LAUNCHER" />
    "android.intent.action.CREATE_SHORTCUT">

主要代码如下:

import android.content.ContentResolver;
import android.content.Intent;
import android.content.Intent.ShortcutIconResource;
import android.database.Cursor;
import android.graphics.BitmapFactory;
import android.net.Uri;
import android.os.Bundle;
public class AddShortCutActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
boolean flag =IfaddShortCut();//如果已经创建,则不需要在创建
if(flag==false){
addShortCut();
}
}
public void addShortCut(){
Intent shortcut = new Intent("com.android.launcher.action.INSTALL_SHORTCUT");
// 设置属性
shortcut.putExtra(Intent.EXTRA_SHORTCUT_NAME, getResources().getString(R.string.app_name));
ShortcutIconResource iconRes = Intent.ShortcutIconResource.fromContext(AddShortCutActivity.this, R.drawable.icon);
shortcut.putExtra(Intent.EXTRA_SHORTCUT_ICON,iconRes);
// 是否允许重复创建
shortcut.putExtra("duplicate", false);
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setFlags(Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
intent.addFlags(Intent.FLAG_ACTIVITY_LAUNCHED_FROM_HISTORY);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
intent.setClass(AddShortCutActivity.this, AddShortCutActivity.class);
// 设置启动程序
System.out.println("createIcon");
shortcut.putExtra(Intent.EXTRA_SHORTCUT_INTENT, intent);
AddShortCutActivity.this.sendBroadcast(shortcut);
}
public boolean IfaddShortCut(){
boolean isInstallShortcut = false ;
final ContentResolver cr = AddShortCutActivity.this.getContentResolver();
//本人的2.2系统是”com.android.launcher2.settings”,网上见其他的为"com.android.launcher.settings"
final String AUTHORITY = "com.android.launcher2.settings";
final Uri CONTENT_URI = Uri.parse("content://" +
AUTHORITY + "/favorites?notify=true");
Cursor c = cr.query(CONTENT_URI,
new String[] {"title","iconResource" },
"title=?",
new String[] {getString(R.string.app_name ) }, null);//XXX表示应用名称。
if(c!=null && c.getCount()>0){
isInstallShortcut = true ;
System.out.println("已创建");
}
return isInstallShortcut ;
}
}
