Android 发送本地广播 以及创建广播接收器

1、创建本地广播接收器

public class MainActivity extends AppCompatActivity{
    private Button mBtn;21     private BindService.MyBinder mMyBinder;
    private MyReceiver mMyReceiver;                       //创建广播接收器类变量
    private LocalBroadcastManager mLocalBroadcastManager; //创建本地广播管理器类变量

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mMyReceiver = new MyReceiver();                                                     //实例化广播接收器 MyReceiver()
        IntentFilter filter = new IntentFilter("com.package.yanglei.action.test");          //动态配置广播接收器action
        mLocalBroadcastManager = LocalBroadcastManager.getInstance(this);                   //广播变量管理器获得本地广播管理器
        mLocalBroadcastManager.registerReceiver(mMyReceiver, filter);                       //注册本地广播


        mBtn = findViewById(R.id.mOnclick);
        mBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                Intent intent = new Intent("com.package.yanglei.action.test");      //创建发送广播的Action
                intent.putExtra(Intent.EXTRA_TEXT, "hi lllllllllll");                //发送携带的数据
                mLocalBroadcastManager.sendBroadcast(intent);                               //发送本地广播
            }
        });

    }

　　//广播接收器
    private class MyReceiver extends BroadcastReceiver {
        @Override
        public void onReceive(Context context, Intent intent) {
            Log.i("hhhhhhh0", intent.getStringExtra(Intent.EXTRA_TEXT));　　//获取文本
        }
    }
}
