本文实例为大家分享了android实现进度条移动效果的具体代码,供大家参考,具体内容如下

CustomViewActivity.java
public class CustomViewActivity extends Activity {
private static final String TAG = "CustomViewActivity";
private TextView tv_schedule;
private View view;
private ProgressBar progressBar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_custom_view);
initView();
}
private void initView() {
initProgressView();
}
private void initProgressView() {
tv_schedule = findViewById(R.id.tv_schedule);
view = findViewById(R.id.view);
progressBar = findViewById(R.id.progressbar);
int finishSpeed = 2;
Log.d(TAG,"finishSpeed="+finishSpeed);
float speedPer = ((float) finishSpeed)/8*100;
Log.d(TAG,"speedPer="+speedPer);
tv_schedule.setText(speedPer+"%");
progressBar.setProgress((int)speedPer);
setTextViewWidth(tv_schedule,view,speedPer);
}
private void setTextViewWidth(TextView textView,View view,float speed) {
Paint paint = new Paint();
float textWidth = paint.measureText(textView.getText().toString());
Log.d(TAG,"textWidth="+textWidth);
LinearLayout.LayoutParams params = (LinearLayout.LayoutParams) textView.getLayoutParams();
LinearLayout.LayoutParams params1 = (LinearLayout.LayoutParams) view.getLayoutParams();
if (textWidth > speed) {
params.weight = textWidth;
params1.weight = 100 - textWidth;
} else {
params.weight = speed;
params1.weight = 100 - speed;
}
}
}
