android - Activity 不启动

Question

当我按下按钮开始新 Activity 时，应用程序转而进入主要 Activity 。
我真的很困惑，因为没有任何错误。我还在 On create of desired activity 中有日志消息 - 它不会弹出。你能告诉我是什么导致了这种奇怪的行为吗？

    public void btnAtcEdit(View v) {
        Log.d("ATS", "i tried to go to ATS believe me");
        try {
            Log.d("ATS", " i tried to go to ATS 2 believe me");
            // convert bitmap to bytearray to pass them in intent
            final BitmapDrawable bitmapDrawable1 = (BitmapDrawable) photo1
                    .getDrawable();
            final Bitmap yourBitmap1 = bitmapDrawable1.getBitmap();
            ByteArrayOutputStream stream1 = new ByteArrayOutputStream();
            yourBitmap1.compress(Bitmap.CompressFormat.PNG, 90, stream1);
            byte[] imm1 = stream1.toByteArray();

            final BitmapDrawable bitmapDrawable2 = (BitmapDrawable) photo2
                    .getDrawable();
            final Bitmap yourBitmap2 = bitmapDrawable2.getBitmap();
            ByteArrayOutputStream stream2 = new ByteArrayOutputStream();
            yourBitmap2.compress(Bitmap.CompressFormat.PNG, 90, stream2);
            byte[] imm2 = stream2.toByteArray();

            final BitmapDrawable bitmapDrawable3 = (BitmapDrawable) photo3
                    .getDrawable();
            final Bitmap yourBitmap3 = bitmapDrawable3.getBitmap();
            ByteArrayOutputStream stream3 = new ByteArrayOutputStream();
            yourBitmap3.compress(Bitmap.CompressFormat.PNG, 90, stream3);

            byte[] imm3 = stream3.toByteArray();
            Intent i = new Intent(AddToCheckActivity.this,
            AddSaveActivity.class);

            i.putExtra("photo1", imm1);
            /*
                        putting more parameters
                        */
            i.putExtra("not_priceFor", not_priceFor);

            startActivity(i);
            stream1.flush();
            stream1.close();
            stream2.flush();
            stream2.close();
            stream3.flush();
            stream3.close();
//          finish();
        } catch (Exception e) {
            Log.d("ATS error", "before entered ATS");
            e.printStackTrace();
        }

    }

添加保存 Activity

@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.aadd_add_edit);
        Log.d("ATS", "was started");
                /*
                some job
                */
                }

Log cat 是空的 它只是显示，那个按钮被按下了。

按钮的 onClickListener 在 xml 中是 defiend

 <Button
                android:id="@+id/btnAtcEdic"
                android:layout_width="0px"
                android:layout_height="match_parent"
                android:layout_margin="0dp"
                android:layout_marginBottom="10sp"
                android:layout_marginLeft="40sp"
                android:layout_marginRight="40sp"
                android:layout_marginTop="10sp"
                android:layout_weight="1"
                android:background="@drawable/button_primary"
                android:drawablePadding="0sp"
                android:onClick="btnAtcEdit"
                android:padding="0dp"
                android:text="Редактировать"
                android:textColor="#FFFFFF" />

有趣的事情 - 在 HTC phons 上总是没有任何错误迹象。

编辑:在我将 imm 表单 Intent 移动到单例后，应用程序似乎可以正常工作

您不能使用应用程序上下文启动 Activity 。您只能使用另一个 Activity Context 启动它们。

以下更改应该可以解决此问题。将

替换为您的 Activity 名称

Intent i = new Intent(<YourCallingActivity>.this, AddSaveActivity.class);

作为引用，这里有一个关于在哪个地方需要哪种上下文的指南:
