在这之后还当我点击该按钮，图像旋转。但位置发生变化，而不是在全屏幕显示。

After that also when I clicked the button image will rotate. but positions is changed and not shown in full screen.

我的requrement是，当我点击该按钮，图像会roatate顺时针方向，将在全屏幕显示。我再次点击按钮图像必须旋转时钟明智和全屏幕显示。同样，当我按一下按钮图像必须旋转。

My requrement is, when I click the button image will be roatate clockwise and will show in full screen. Again I click the button image must be rotate clock wise and show in full screen. Likewise when I click the button image must be rotate.

因此​​，有人可以帮我吗？如果你可以给我一个样品code或将非常大大appriciated链接。

Therefore can someone help me? If you can give me a sample code or a link that will be very much appriciated.

下面是code，我正在努力，

Here is the code which I'm trying,

的main.xml

<merge xmlns:android="http://schemas.android.com/apk/res/android" >

    <ImageView
        android:id="@+id/imgView"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_weight="1"
        android:scaleType="fitXY"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:adjustViewBounds="true"
        android:src="@drawable/matterhorn"
        />

    <Button
        android:id="@+id/btnRotate"
        android:layout_width="65dp"
        android:layout_height="35dp"
        android:layout_gravity="bottom|left"
        android:layout_marginLeft="190dp"
        android:layout_marginBottom="15dp"
        android:layout_weight="1"
        android:background="@android:color/transparent"
        android:drawableLeft="@drawable/btn_icon_rotate"
        >
    </Button>

</merge>

这是我的主要活动MainActivity.java

package com.imageview.rotate;

import android.os.Bundle;
import android.app.Activity;
import android.graphics.Matrix;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.ImageView.ScaleType;

public class MainActivity extends Activity implements OnClickListener{

    private Button btnRotate;
    private ImageView imgview;

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

        imgview = (ImageView) findViewById(R.id.imgView);

        btnRotate = (Button) findViewById(R.id.btnRotate);
        btnRotate.setOnClickListener(this);

    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {

        case R.id.btnRotate:
            Matrix matrix=new Matrix();
            imgview.setScaleType(ScaleType.MATRIX);   //required
            matrix.postRotate((float) 180f, imgview.getDrawable().getBounds().width()/2, imgview.getDrawable().getBounds().height()/2);
            imgview.setImageMatrix(matrix);


            break;

        }
    }


}

在此先感谢。

Thanks in advance.

推荐答案

不错

创建 button_rotate.xml 在动画文件夹：

<?xml version="1.0" encoding="utf-8"?>

<rotate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="1000"
    android:fromDegrees="0"
    android:interpolator="@android:anim/linear_interpolator"
    android:pivotX="50%"
    android:pivotY="50%"
    android:toDegrees="360" />

现在的Java文件中创建动画：

Now create animation in Java file:

/* Get ImageView Object */
ImageView iv = (ImageView) view.findViewById(R.id.refresh_action_view);

/* Create Animation */
Animation rotation = AnimationUtils.loadAnimation(context, R.anim.refresh_button_anim);
rotation.setRepeatCount(Animation.INFINITE);

/* start Animation */
iv.startAnimation(rotation);

有关停止动画：

iv.clearAnimation();
