android 彈出輸入框，並且預設全選預設值

 其實很簡單，把selectall放在show後面就行了

 

final EditText input = new EditText(this); input.setText("XXX"); new AlertDialog.Builder(this).XXXX.show(); input.selectAll()          final EditText input = new EditText(this);input.setText("XXX");new AlertDialog.Builder(this).XXXX.show();input.selectAll()

  

再補充下，如果需要彈出輸入對話方塊，並且全選預設值，並且彈出IME，結合上面的selectall和下面的程式碼片段即可

 

final AlertDialog dialog = ...;  editText.setOnFocusChangeListener(new View.OnFocusChangeListener() {     @Override     public void onFocusChange(View v, boolean hasFocus) {         if (hasFocus) {             dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);         }     } }); final AlertDialog dialog = ...;editText.setOnFocusChangeListener(new View.OnFocusChangeListener() {    @Override    public void onFocusChange(View v, boolean hasFocus) {        if (hasFocus) {            dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);        }    }});
