android 關於截屏

在android4.0以下用這個方法：

 

private void cutScreen(){View v = getLayoutInflater().inflate(R.layout.activity_main, null);//開啟映像緩衝v.setDrawingCacheEnabled(true);//v.buildDrawingCache();//測量view的大小v.measure(MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED), MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));//發送位置和尺寸到View及其所有的子View/*View v = this.getWindow().getDecorView();v.setDrawingCacheEnabled(true);v.buildDrawingCache();*/v.layout(0, 0, v.getMeasuredWidth(), v.getMeasuredHeight());LogHelper.LogV("" + v.getMeasuredWidth() + " " + v.getMeasuredHeight());try {Bitmap bitmap = v.getDrawingCache();FileOutputStream fos = new FileOutputStream("/sdcard/test.png");bitmap.compress(CompressFormat.PNG, 100, fos);fos.close();LogHelper.LogE("截屏成功");} catch (Exception e) {// TODO Auto-generated catch blockLogHelper.LogE("截屏失敗 + " + e.getMessage());e.printStackTrace();}}

如果是android 4.0以上可以這樣用：

 

 

private void cutScreen(){/*View v = getLayoutInflater().inflate(R.layout.activity_main, null);//開啟映像緩衝v.setDrawingCacheEnabled(true);//v.buildDrawingCache();//測量view的大小v.measure(MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED), MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));*///發送位置和尺寸到View及其所有的子ViewView v = this.getWindow().getDecorView();v.setDrawingCacheEnabled(true);v.buildDrawingCache();v.layout(0, 0, v.getMeasuredWidth(), v.getMeasuredHeight());LogHelper.LogV("" + v.getMeasuredWidth() + " " + v.getMeasuredHeight());try {Bitmap bitmap = v.getDrawingCache();FileOutputStream fos = new FileOutputStream("/sdcard/test.png");bitmap.compress(CompressFormat.PNG, 100, fos);fos.close();LogHelper.LogE("截屏成功");} catch (Exception e) {// TODO Auto-generated catch blockLogHelper.LogE("截屏失敗 + " + e.getMessage());e.printStackTrace();}}
