Java 以编程方式在drawable下创建editText

我有一个editText:@+id/editText1，我想在onClick方法之后在R.drawable.sqwhite下面实例化它

我的问题是，drawable不是通过XML创建的，我不确定如何让editText1直接显示在R.drawable.sqwhite下面

爪哇： XML:

您能提供

添加新图像到屏幕（resourceId）

的代码吗？完成-如果有任何问题，请告诉我！我理解你的代码有点困难。在XML文件中，为什么在id为

editText1

的EditText上方有一个没有id的ImageView？这是您希望位于EditText上方的ImageView吗？您可以删除它-它目前不起任何作用（这是我尝试过的一些疑难解答遗留下来的）。在这种情况下，我实际上会保留ImageView并在XML文件中为其分配一个id，在XML文件中指定ImageView应位于EditText上方，然后从java代码中以编程方式更改此ImageView中的drawable/image。

public void onClickAddImage(View v) {
    addNewImageToScreen();
}

public void addNewImageToScreen() {
    int resourceId = R.drawable.sqwhite;
    addNewTextToScreen();
    int m = mImageCount % 3;

    if (m == 1)
        resourceId = R.drawable.sqdrk;

    else if (m == 2)
        resourceId = R.drawable.sqwhite;
    addNewImageToScreen(resourceId);

}

private void addNewTextToScreen() {
    // TODO Auto-generated method stub

    et.setVisibility(View.VISIBLE);
    if (isErase) {
        tx.setText(et.getText().toString());
    } else {
        tx.setText("");
        et.setVisibility(View.GONE);
    }
    isErase = !isErase;
}


public void addNewImageToScreen(int resourceId) {
    if (mLastNewCell != null)
        mLastNewCell.setVisibility(View.GONE);
    et.setVisibility(View.VISIBLE);
    FrameLayout imageHolder = (FrameLayout) findViewById(R.id.image_source_frame);
    if (imageHolder != null) {
        FrameLayout.LayoutParams lp = new FrameLayout.LayoutParams(
                LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT,
                Gravity.CENTER);
        ImageCell newView = new ImageCell(this);
        newView.setImageResource(resourceId);
        imageHolder.addView(newView, lp);
        newView.mEmpty = false;
        newView.mCellNumber = -1;
        mLastNewCell = newView;
        mImageCount++;

        // Have this activity listen to touch and click events for the view.
        newView.setOnClickListener(this);
        newView.setOnLongClickListener(this);
        newView.setOnTouchListener(this);

    }
}
