Question

我有这个类，它在每次点击后配置drawable的图像。

*******
int mProgressBar;
int mProgressBarBg;
boolean check = true;
ProgressBar progress;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    progress = (ProgressBar) findViewById(R.id.progressBar1);
    progress.setProgress(50);
    findViewById(R.id.button1).setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            if(check) {
                mProgressBarBg = R.drawable.bg_bar_progress;
                mProgressBar = R.drawable.progress_quest_green;
                check = false;
            } else {
                mProgressBarBg = R.drawable.bg_bar_progress_orange;
                mProgressBar = R.drawable.progress_quest_orange;
                check = true;
            }
            findViewById(R.id.progressBar).setBackgroundResource(mProgressBarBg);
            Drawable colorDrawable = getResources().getDrawable(mProgressBar);
            Rect bounds = progress.getProgressDrawable().getBounds();
            progress.setProgressDrawable(colorDrawable);
            progress.getProgressDrawable().setBounds(bounds);
        }
    });
}

问题：点击后未显示进度。我该如何解决？

Answer 1

这可能会有所帮助：Android ProgressBar.setProgressDrawable only works once?

这个答案：
＆＃34;为了我的工作，我做了你说的话并添加：mySeekBar.setProgress（mySeekBar.getProgress（）+ 1）; mySeekBar.setProgress（mySeekBar.getProgress（） - 1）;这样做我强行移动，但保持相同的位置。 - Derzu＆＃34;
