如何在某个角度倾斜一个子布局 [英] How to tilt a child layout at some angle

问题描述

我试过了自定义视图和倾斜的形象成功45度，但我想倾斜一定角度，整个儿layoout所以，无论我会在子布局的添加将automactically平铺..仅供参考，请取看看附加的图片

连我都试过这code，但它不会帮助

 公共类CustomLinear扩展的LinearLayout {
私人矩阵mForward =新的Matrix（）;
私人矩阵mReverse =新的Matrix（）;
私人浮动[] = mTemp新的浮动[2];公共CustomLinear（上下文的背景下）{
超级（上下文）;
}公共CustomLinear（上下文的背景下，ATTRS的AttributeSet）{
超（背景下，ATTRS）;
}@覆盖
保护无效dispatchDraw（帆布油画）{canvas.rotate（75，的getWidth（）/ 2，的getHeight（）/ 2）;mForward = canvas.getMatrix（）;
mForward.invert（mReverse）;
canvas.save（）;
canvas.setMatrix（mForward）; //这是我们需要使用的矩阵
                                        //触摸事件的适当定位
super.dispatchDraw（画布）;
canvas.restore（）;
无效（）;
}@覆盖
公共布尔dispatchTouchEvent（MotionEvent事件）{
event.setLocation（的getWidth（） -  event.getX（），的getHeight（） -  event.getY（））;
返回super.dispatchTouchEvent（事件）;
}}
 

解决方案

我的事情有可能使用的旋转动画。你可以用 0时长在On_create孩子整个童年布局应用动画。

下面是动画code

 ＆LT;？XML版本=1.0编码=UTF-8＆GT？;
    ＆LT;旋转
     的xmlns：机器人=htt​​p://schemas.android.com/apk/res/android
        机器人：fromDegrees =0
        机器人：toDegrees = -  90
        机器人：pivotX =50％
        机器人：pivotY =50％
        机器人：时间=0
        机器人：fillAfter =真正的＆GT;
    ＆LT; /旋转＆GT;
 

您可以设置旋转角度根据自己的需要。

然后使用给定的code在活动的onCreate，

  @覆盖
  公共无效的onCreate（包B）{
  super.onCreate（二）;
     的setContentView（R.layout.myscreen）;
     动画rotate_anim = AnimationUtils.loadAnimation（这一点，R.anim.rotation）;
     LayoutAnimationController anim_controller =新LayoutAnimationController（rotate_anim，0）;
     的FrameLayout布局=（的FrameLayout）findViewById（R.id.MyScreen_ContentLayout）;
     layout.setLayoutAnimation（anim_controller）;
 }
 

I've tried the custom view and tilt the image to 45 degree successfully but I want to tilt the whole child layoout at some angle so that whatever I'll add in that child layout will automactically tiled .. For reference please take a look at the attached picture

even I have tried this code but it wont help

public class CustomLinear extends LinearLayout{
private Matrix mForward = new Matrix();
private Matrix mReverse = new Matrix();
private float[] mTemp = new float[2];

public CustomLinear(Context context) {
super(context);
}

public CustomLinear(Context context, AttributeSet attrs) {
super(context, attrs);
}

@Override
protected void dispatchDraw(Canvas canvas) {

canvas.rotate(75, getWidth() / 2, getHeight() / 2);

mForward = canvas.getMatrix();
mForward.invert(mReverse);
canvas.save();
canvas.setMatrix(mForward); // This is the matrix we need to use for
                                        // proper positioning of touch events
super.dispatchDraw(canvas);
canvas.restore();
invalidate();
}

@Override
public boolean dispatchTouchEvent(MotionEvent event) {
event.setLocation(getWidth() - event.getX(), getHeight() - event.getY());
return super.dispatchTouchEvent(event);
}

}

解决方案

I thing it is possible using rotate animation. you can apply animation on the whole child layout with 0 duration in On_create.

Here is the animation code

<?xml version="1.0" encoding="utf-8"?>
    <rotate
     xmlns:android="http://schemas.android.com/apk/res/android"
        android:fromDegrees="0"
        android:toDegrees="-90"
        android:pivotX="50%"
        android:pivotY="50%"
        android:duration="0"
        android:fillAfter="true">
    </rotate>

You can set the rotation angle as per your need.

Then use given code in your Activity's onCreate,

  @Override
  public void onCreate(Bundle b) {
  super.onCreate(b);
     setContentView(R.layout.myscreen);
     Animation rotate_anim = AnimationUtils.loadAnimation(this, R.anim.rotation);
     LayoutAnimationController anim_controller = new LayoutAnimationController(rotate_anim, 0);
     FrameLayout layout = (FrameLayout)findViewById(R.id.MyScreen_ContentLayout);
     layout.setLayoutAnimation(anim_controller);
 }
