Android 代码的屏幕截图
我需要捕获当前屏幕的屏幕截图,因此我在Android 代码的屏幕截图,android,screen,screenshot,capture,Android,Screen,Screenshot,Capture,我需要捕获当前屏幕的屏幕截图,因此我在 protected void onPause() { // TODO Auto-generated method stub super.onPause(); LinearLayout v = (LinearLayout) findViewById(R.id.mainLayout); v.setDrawingCacheEnabled(true); // this is the important code :)
protected void onPause() {
// TODO Auto-generated method stub
super.onPause();
LinearLayout v = (LinearLayout) findViewById(R.id.mainLayout);
v.setDrawingCacheEnabled(true);
// this is the important code :)
// Without it the view will have a
// dimension of 0,0 and the bitmap will
// be null
v.measure(MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED),
MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
//v.layout(0, 0, v.getMeasuredWidth(), v.getMeasuredHeight());
v.layout(0, 0, v.getWidth(), v.getHeight());
v.buildDrawingCache(true);
Bitmap bm = Bitmap.createBitmap(v.getDrawingCache());
v.setDrawingCacheEnabled(false); //
if (bm != null) {
try {
String path = Environment.getExternalStorageDirectory()
.toString();
OutputStream fOut = null;
File file = new File(path, "screentest.jpg");
fOut = new FileOutputStream(file);
bm.compress(Bitmap.CompressFormat.JPEG, 85, fOut);
fOut.flush();
fOut.close();
Log.e("ImagePath", "Image Path : "
+ MediaStore.Images.Media.insertImage(
getContentResolver(), file.getAbsolutePath(),
file.getName(), file.getName()));
} catch (Exception e) {
e.printStackTrace();
}
}
}
这段代码对我来说很好,但我需要在屏幕加载完成后捕获屏幕
我也尝试过onpostreate(),但都是徒劳的
我还尝试调用onPause()方法中的代码,但由于动画的原因,屏幕从右侧和底部修剪了一点。。。所以我甚至不能去做
现在轮到你分享你的专业知识了
非常感谢您的任何建议 试试这个:
public void onCreate(Bundle savedInstanceState) {
LinearLayout v = (LinearLayout) findViewById(R.id.mainLayout);
v.setDrawingCacheEnabled(true);
v.post(new Runnable() {
public void run() {
// Code to take screenshot
});
}
}
创建时的公共void(Bundle savedInstanceState){
LinearLayout v=(LinearLayout)findViewById(R.id.mainLayout);
v、 setDrawingCacheEnabled(真);
v、 post(新的Runnable(){
公开募捐{
//截图代码
});
}
}
