[android]android自動化測試十二之程式碼控制截圖

該方法適用於對某個Activity進行截圖，不包含狀態列，在使用之前要保證view載入完畢才可以進行使用。

import java.io.FileOutputStream;
import java.io.IOException;

import android.app.Activity;
import android.graphics.Bitmap;
import android.graphics.Rect;
import android.util.Log;
import android.view.View;

    // 獲取指定Activity的截圖，儲存到png檔案
    private static Bitmap takeScreenShot(Activity activity) {
        // View是你需要截圖的View
        View view = activity.getWindow().getDecorView();
        view.setDrawingCacheEnabled(true);
        view.buildDrawingCache();
        Bitmap b1 = view.getDrawingCache();

        // 去掉標題欄
        // Bitmap b = Bitmap.createBitmap(b1, 0, 25, 320, 455);
        Bitmap b = Bitmap.createBitmap(b1, 0, statusBarHeight, width, height
                - statusBarHeight);
        view.destroyDrawingCache();
