为什么我无法使用“setImageRecource”来更改 Android Studio 中 ImageView 使用的可绘制对象？

Question

I'm learning how to develop apps for Android, I´m familiar with Java through school courses. Currently, I m developing a small TicTacToe app for exercise purpose and I´m trying to show a cross instead of a circle but Android Studio cant compile setImageRecource` command even though in every damn online forum this method is recommended.

I've already tried things like set setBackgroundRecource but all these things doesn't fulfill my purpose...

The Java Code:

 public void click(View pView){
    if(getActivePlayer()== 1){
        if(s1.getSymbol().equals("cross")){
            pView.setImageResource(R.drawable.circle); //claims cannot Resolve method 'setIMageRecource(int)'
        }
        else{
            pView.setImageResource(R.drawable.cross); //claims cannot Resolve method 'setIMageRecource(int)'
        }
    }
    else if(getActivePlayer()==2){
        if(s2.getSymbol().equals("circle")){
            pView.setImageResource(R.drawable.circle); //claims cannot Resolve method 'setIMageRecource(int)'
        }
        else{
            pView.setImageResource(R.drawable.cross); //claims cannot Resolve method 'setIMageRecource(int)'
        }
    }
    pView.setY(-1000);
    pView.setAlpha(1);
    pView.animate().translationYBy(1000).setDuration(1000);
    if (getActivePlayer() == 1){
        setActivePlayer(2);
        String checker = "aktive player ist gerade" + getActivePlayer();
        Log.i("INfo", checker);
    }
    else{
        setActivePlayer(1);
        String checker = "aktive player ist gerade" + getActivePlayer();
        Log.i("INfo", checker);
    }

}

In XML:

 <ImageView
            android:id="@+id/field4"
            android:layout_width="120dp"
            android:layout_height="120dp"
            android:onClick="click"
            app:srcCompat="@drawable/circle" />

Answer 1

You can use ImageView.setImageDrawable(Context impact.getDrawable(mContext, R.drawable.cross));

Here mContext is globally declared as your activity reference.

Answer 2

您需要像这样将View为ImageView 。

((ImageView) pView).setImageResource(R.drawable.cross);
