Android 监听长时单击（OnLongClickListener）

/res/layout/main.xml代码如下：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="长时单击事件" />

    <Button
        android:id="@+id/longBtn"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="长按我嗷"
        android:layout_marginTop="10dp"/>

</LinearLayout>

Java代码如下：

package com.demo.android.click;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

public class MainActivity extends Activity {
    private Button longBtn;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        longBtn=(Button) findViewById(R.id.longBtn);
        longBtn.setOnLongClickListener(new View.OnLongClickListener() {
            @Override
            public boolean onLongClick(View v) {
                Toast.makeText(MainActivity.this, "OnLongClickListener事件", Toast.LENGTH_SHORT).show();
                return false;
            }
        });
    }
}
