package xidian.dy.com.chujia;import android.content.Context;import android.content.Intent;import android.content.SharedPreferences;import android.os.Bundle;import android.support.v7.app.AppCompatActivity;import android.view.View;import android.widget.Button;public class MainActivity extends AppCompatActivity {    SharedPreferences sp;    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        sp = getSharedPreferences("hate", Context.MODE_PRIVATE);        Button button = (Button) findViewById(R.id.sure);        if(button != null)            button.setOnClickListener(new View.OnClickListener() {                @Override                public void onClick(View v) {                    Intent intent = new Intent();                    intent.setAction("com.dy.xd.test");                    sendBroadcast(intent);                }            });    }}
