Android搜索栏更改文本+格式editText(Android seekbar change text + format editText)

Android搜索栏更改文本+格式editText(Android seekbar change text + format editText)

当搜索栏更改时，我想更新editText并更改进度（这已成功实现）。 现在我如何以$ currency格式格式化editText值，例如$ 200,000。 搜索栏与此类似。

SeekBar sk=(SeekBar)findViewById(R.id.seekBar1); final EditText tv=(EditText)findViewById(R.id.EditText1); sk.setOnSeekBarChangeListener(new OnSeekBarChangeListener() { public void onStopTrackingTouch(SeekBar arg0) { // TODO Auto-generated method stub } public void onStartTrackingTouch(SeekBar arg0) { // TODO Auto-generated method stub } public void onProgressChanged(SeekBar arg0, int arg1, boolean arg2) { // TODO Auto-generated method stub tv.setText("Seek bar value is"+ arg1); } });

我只想要一个关于在哪里格式化editText的提示，以便在搜索栏更改时将天数显示为$ 200,000？

When the seekbar change i want to update the editText with the progress changed(This was successfully achieved). Now how can i format the editText value in $currency format e.g.$200,000. The seekbar is similar to this.

SeekBar sk=(SeekBar)findViewById(R.id.seekBar1); final EditText tv=(EditText)findViewById(R.id.EditText1); sk.setOnSeekBarChangeListener(new OnSeekBarChangeListener() { public void onStopTrackingTouch(SeekBar arg0) { // TODO Auto-generated method stub } public void onStartTrackingTouch(SeekBar arg0) { // TODO Auto-generated method stub } public void onProgressChanged(SeekBar arg0, int arg1, boolean arg2) { // TODO Auto-generated method stub tv.setText("Seek bar value is"+ arg1); } });

I just want a tips in where to format the editText to display days as $200,000.. when seekbar change ?

最满意答案

您可以使用DecimalFormat

public void onProgressChanged(SeekBar arg0, int arg1, boolean arg2) {     // TODO Auto-generated method stub DecimalFormat df = new DecimalFormat("$###,###"); String value = df.format(arg1); System.out.println(value); // will output "$200,000"  if arg1 = 200000   tv.setText("Seek bar value is "+ value); }

You can use DecimalFormat

public void onProgressChanged(SeekBar arg0, int arg1, boolean arg2) {     // TODO Auto-generated method stub DecimalFormat df = new DecimalFormat("$###,###"); String value = df.format(arg1); System.out.println(value); // will output "$200,000"  if arg1 = 200000   tv.setText("Seek bar value is "+ value); }
