Android中长按监听的使用

  长按监听的使用：

activity_main.xml布局

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.wdl.onlongclicklistenerimpl.onlongclicklistenerimpl.MainActivity">

<TextView
android:gravity="center"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="点击长按"
android:id="@+id/tv"
android:textSize="20dp" />
</RelativeLayout>


MainActivity.java:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TextView tv=(TextView) findViewById(R.id.tv);
//长按监听
tv.setOnLongClickListener(new View.OnLongClickListener() {
@Override
public boolean onLongClick(View v) {
Toast.makeText(MainActivity.this,"长按成功",Toast.LENGTH_SHORT).show();
return true;
}
});
}
