在textview中显示值时出错

Question

I am stuck in some problem and i search alot but did not find any solution here is my code

   private void rotateDialer(float degrees, int angleMove) {
    angleMove = conversionAngles(angleMove);
    // txt.setText(""+angleMove);
    // matrix.postRotate(degrees, dialerWidth / 2, dialerHeight / 2);
    // dialer.setImageMatrix(matrix);

    if (angleMove < 36 && angleMove >= 0) {
        settingMinutesNeedle(36);
        // /addAngles = addAngles + 36;
    } else if (angleMove >= 36 && angleMove < 72)
        settingMinutesNeedle(72);
    else if (angleMove >= (36 * 2) && angleMove < (36 * 3)) {
         Toast.makeText(getApplicationContext(),
         "move angle "+angleMove,Toast.LENGTH_SHORT).show();


//error here         tvval.setText(angleMove);




settingMinutesNeedle(36 * 3);
    } else if (angleMove >= (36 * 3) && angleMove < (36 * 4))
        settingMinutesNeedle(36 * 4);
    else if (angleMove >= (36 * 4) && angleMove < (36 * 5))
        settingMinutesNeedle(36 * 5);
    else if (angleMove >= (36 * 5) && angleMove < (36 * 6))
        settingMinutesNeedle(36 * 6);
    else if (angleMove >= (36 * 6) && angleMove < (36 * 7))
        settingMinutesNeedle(36 * 7);
    else if (angleMove >= (36 * 7) && angleMove < (36 * 8))
        settingMinutesNeedle(36 * 8);
    else if (angleMove >= (36 * 8) && angleMove < (36 * 9))
        settingMinutesNeedle(36 * 9);
    else if (angleMove >= (36 * 9) && angleMove < (36 * 10))
        settingMinutesNeedle(36 * 10);
    // count = count + 1;
}

when i toast value it do not give any error but when i set it in textview it shows "Exception dispatching input event"

How i can resolve it?

Answer 1

Use

 tvval.setText(String.valueOf(angleMove));

angleMove is int. setText has methods one that takes int which looks for resource with the id mentioned if not found you get ResourceNotFoundException and the other than takes CharacterSequence . So you need to use String.valueOf(angleMove)

Answer 2

like you did above, do

tvval.setText(""+angleMove);

because you can't directly set an int or float value to your textview

Answer 3

Just try below code:

tvval.setText(String.valueOf(angleMove));

I think this will work for sure.

Answer 4

angleMove is int , abd TextView.setText() expects a CharSequence...

So, You can do as following:

tvval.setText(angleMove + "");

Answer 5

尝试这个：

tvval.setText(angleMove + "");
