OnTouchListener

1.布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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" android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:orientation="vertical"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="helloworld.com.inspur.app4.MainActivity">
 
    <TextView android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="hah"
        android:id="@+id/tv_1"
        />
    <TextView android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="hahahh"
        android:id="@+id/tv_2"
         />
</LinearLayout>

（2）逻辑代码的实现

package helloworld.com.inspur.app4;
 
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.MotionEvent;
import android.view.View;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;
 
public class MainActivity extends AppCompatActivity {
    private TextView tv1;
    private TextView tv2;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        tv1=(TextView)findViewById(R.id.tv_1);
        tv2=(TextView)findViewById(R.id.tv_2);
        tv2.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
               switch (event.getAction())
                {
                    case MotionEvent.ACTION_UP:
                        Toast.makeText(MainActivity.this,"按下",Toast.LENGTH_SHORT).show();
                        break;
                    case MotionEvent.ACTION_MOVE:
                        Toast.makeText(MainActivity.this,"移动",Toast.LENGTH_SHORT).show();
                        break;
                    case MotionEvent.ACTION_DOWN:
                        Toast.makeText(MainActivity.this,"松开",Toast.LENGTH_SHORT).show();
                        break;
                }
 
                return true;
            }
        });
 
    }
}
