18 Ui美化 剪切动画clip

• 输入0 - 10000 让图片根据数值显示部分图片

• 在工程文件的res/drawable/新建clip文件

  <?xml version="1.0" encoding="utf-8"?>
  <clip xmlns:android="http://schemas.android.com/apk/res/android"
      android:clipOrientation="horizontal"
      android:drawable="@drawable/android1"
      android:gravity="left" >
  <!--
  android:clipOrientation="horizontal"剪切方向
      android:drawable="@drawable/android1"设置图片源
      android:gravity="left"剪切从哪里开始
   -->
  </clip>

• 使用

package com.fmy.lianxi;

import android.R.transition;
import android.app.Activity;
import android.graphics.drawable.ClipDrawable;
import android.graphics.drawable.Drawable;
import android.graphics.drawable.TransitionDrawable;
import android.os.Bundle;
import android.view.View;
import android.widget.ImageView;
import android.widget.Toast;

public class MainActivity extends Activity {

    private ImageView iv;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        iv = (ImageView) findViewById(R.id.iv);

    }

    public void click(View v) {
        ClipDrawable drawable = (ClipDrawable) iv.getDrawable();
//      level 0 - 10000 之间  大于等于10000显示完全 小于等于0完全不显示
        int level = drawable.getLevel();
        drawable.setLevel(level+10000);
    }

}

• 布局文件

<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:orientation="vertical" >

    <ImageView
        android:id="@+id/iv"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/myclip" />
</LinearLayout>
