根据EditText值更改SeekBar进度

etOne = (EditText) findViewById(R.id.etSyst);
etOne.addTextChangedListener(new TextWatcher() {
public void afterTextChanged(Editable s) {
int i = Integer.parseInt(s.toString());
if (i >= 70 && i <= 190) {
sbSyst.setProgress( i - 70); // This ensures 0-120 value for seekbar
}
}
public void beforeTextChanged(CharSequence s, int start, int count, int after) {}

 public void onTextChanged(CharSequence s, int start, int before, int count) {}        });
