长按圆形按钮结束事件，有颜色变化的效果，有源码

              长按圆形按钮结束事件，有颜色变化的效果

项目中用到了长按圆形按钮触发结束当前事件的需求：此次讲的是

长按结束按钮进入另一个界面的需求实现。

 

                               

具体实现比较简单：有用到了OnTouchListener事件，还有动态改变控件

高度的方法，用到了Handler。

具体代码如下：

public class Bo1MainActivity extends Activity implements OnClickListener {

private Button mButton;

private View frameLayout1;

private ImageView imageView2;

private Handler mHandler=new Handler(); 

private LayoutParams params;

private int mHeight;

private boolean isClick;

@Override
protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

mButton = (Button) findViewById(R.id.button1);

imageView2 = (ImageView) findViewById(R.id.imageView2);

frameLayout1 = findViewById(R.id.frameLayout1);

params = frameLayout1.getLayoutParams();

                mHeight = params.height;

mButton.setOnTouchListener(new OnTouchListener() {

@Override
public boolean onTouch(View view, MotionEvent event) {

switch (event.getAction()) {

case MotionEvent.ACTION_DOWN:

isClick=true;

                                        startplay();

break;

case MotionEvent.ACTION_UP:

isClick=false;

endplay();

break;

default:

break;

}

return false;
}


});
}

private void endplay() {

params.height=mHeight;

frameLayout1.setLayoutParams(params);

}


private void startplay() {

mHandler.post(new Runnable() {

@Override
public void run() {

if (isClick) {

params.height+=3;

if (params.height>=imageView2.getHeight()) {

params.height=imageView2.getHeight();

startActivity(new Intent(Bo1MainActivity.this, Bo2Activity.class));

}else{

mHandler.postDelayed(this, 20);

}

frameLayout1.setLayoutParams(params);

}
}
});

}


@Override
public void onClick(View v) {
}

}

布局文件：

<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.example.test_.Bo1MainActivity" >


    <Button
        android:id="@+id/button1"
        android:layout_width="100dp"
        android:layout_height="80dp"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="20dp"
        android:text="长按点击"
         />


    <ImageView
        android:id="@+id/imageView2"
        android:layout_width="180dp"
        android:layout_height="180dp"
        android:layout_centerInParent="true"
        android:src="@drawable/circle2" />


    <FrameLayout
        android:id="@+id/frameLayout1"
        android:layout_width="wrap_content"
        android:layout_height="90dp"
        android:layout_alignBottom="@+id/imageView2"
        android:layout_alignLeft="@+id/imageView2" >


        <ImageView
            android:id="@+id/imageView1"
            android:layout_width="180dp"
            android:layout_height="180dp"
            android:layout_gravity="bottom"
            android:scaleType="fitEnd"
            android:src="@drawable/circle" />
    </FrameLayout>


</RelativeLayout>

其中几个圆的shape图：

circle:XML

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval" >

    <solid android:color="#FF0060" />

</shape>

circle2:xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval" >

    <solid android:color="#A11E50" />

</shape>

跳转页面如下：

public class Bo2Activity extends Activity {


@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_b);
}

}
