Android连续截屏代码

以下是一个简单的 Android 连续截屏代码示例：

public class MainActivity extends AppCompatActivity {

    private Handler handler = new Handler();
    private int delay = 1000; // 截屏间隔时间，单位毫秒

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        handler.postDelayed(new Runnable() {
            @Override
            public void run() {
                takeScreenshot();
                handler.postDelayed(this, delay);
            }
        }, delay);
    }

    private void takeScreenshot() {
        try {
            // 获取屏幕截图
            View view = getWindow().getDecorView().getRootView();
            view.setDrawingCacheEnabled(true);
            Bitmap bitmap = Bitmap.createBitmap(view.getDrawingCache());
            view.setDrawingCacheEnabled(false);

            // 保存截图到文件
            String filename = "screenshot_" + System.currentTimeMillis() + ".png";
            File file = new File(Environment.getExternalStorageDirectory(), filename);
            FileOutputStream fos = new FileOutputStream(file);
            bitmap.compress(Bitmap.CompressFormat.PNG, 100, fos);
            fos.flush();
            fos.close();

            Log.d("MainActivity", "Screenshot saved to " + file.getAbsolutePath());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

这个示例代码会每隔一定时间截取一张屏幕截图，并保存到外部存储器中。注意需要在 AndroidManifest.xml 中添加读写外部存储器的权限：

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
