如果你不需要沉降效果那么你把下面的代码删除掉即可:
if (mReverse) {
// 正向改变Z轴角度
camera.translate(0.0f, 0.0f, mDepthz * interpolatedTime);
} else {
// 反向改变Z轴角度
camera.translate(0.0f, 0.0f, mDepthz * (1.0f - interpolatedTime));
}
好了核心代码已经上完，下面是主界面代码：
package com.test.rotateanimation;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.FrameLayout;
import android.widget.LinearLayout;
import com.test.view.RotateAnimationUtil;
public class MainActivity extends Activity {
private FrameLayout container;
private LinearLayout container1;
private LinearLayout container2;
private RotateAnimationUtil rotateAnimationUtil;
private Button bt_towhile;
private Button bt_toblack;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initView();
bt_towhile.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
rotateAnimationUtil.applyRotateAnimation(1, 0, 90);
}
});
bt_toblack.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
rotateAnimationUtil.applyRotateAnimation(-1, 0, -90);
}
});
// 设置当前View控件的缓存
container
.setPersistentDrawingCache(ViewGroup.PERSISTENT_ANIMATION_CACHE);
}
private void initView() {
container = (FrameLayout) findViewById(R.id.container);
bt_toblack = (Button) findViewById(R.id.bt_toblack);
bt_towhile = (Button) findViewById(R.id.bt_towhile);
container1 = (LinearLayout) findViewById(R.id.container1);
container2 = (LinearLayout) findViewById(R.id.container2);
rotateAnimationUtil = new RotateAnimationUtil(container, container1,
container2);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
