如何在单击按钮时截取屏幕截图任何人都可以提供android代码

Question

我想在单击按钮时截取当前屏幕的屏幕截图。任何人都可以提供 Android 代码吗？我还需要将图像保存在图库中。这就是我尝试过的

public class CaptureScreenShots extends Activity {
LinearLayout L1;
ImageView image;
 @Override
     protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.screen_shots);
    L1 = (LinearLayout) findViewById(R.id.LinearLayout01);
    Button but = (Button) findViewById(R.id.munchscreen);
    but.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            View v1 = L1.getRootView();
            v1.setDrawingCacheEnabled(true);
            Bitmap bm = v1.getDrawingCache();
            BitmapDrawable bitmapDrawable = new BitmapDrawable(bm);
            image = (ImageView) findViewById(R.id.screenshots);
            image.setBackgroundDrawable(bitmapDrawable);
        }
    });
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.screen_shots, menu);
    return true;
}

}

Answer 1

设置按钮点击监听器

share = (Button)findViewById(R.id.share);
share.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        Bitmap bitmap = takeScreenshot();
        saveBitmap(bitmap);

    }
});

那么你必须创建两个方法

public Bitmap takeScreenshot() {
View rootView = findViewById(android.R.id.content).getRootView();
rootView.setDrawingCacheEnabled(true);
return rootView.getDrawingCache();
}

public void saveBitmap(Bitmap bitmap) {
File imagePath = new File(Environment.getExternalStorageDirectory() + "/screenshot.png");
FileOutputStream fos;
try {
    fos = new FileOutputStream(imagePath);
    bitmap.compress(Bitmap.CompressFormat.PNG, 100, fos);
    fos.flush();
    fos.close();
} catch (FileNotFoundException e) {
    Log.e("GREC", e.getMessage(), e);
} catch (IOException e) {
    Log.e("GREC", e.getMessage(), e);
}
}

将此代码添加到您的应用程序中后，运行该应用程序并检查您的本地存储，您已经创建了整个页面的屏幕截图。
