Android: show soft keyboard automatically when focus is on an EditText
I'm showing an input box using AlertDialog . The EditText inside the dialog itself is automatically focused when I call AlertDialog.show() , but the soft keyboard is not automatically shown.
How do I make the soft keyboard automatically show when the dialog is shown? (and there is no physical/hardware keyboard). Similar to how when I press the Search button to invoke the global search, the soft keyboard is automatically shown.
You can create a focus listener on the EditText on the AlertDialog , then get the AlertDialog 's Window . From there you can make the soft keyboard show by calling setSoftInputMode .
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);
}
}
});
For showing keyboard use:
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED,0);
For hiding keyboard use:
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(view.getWindowToken(),0);
您可以在创建对话框后立即请求软键盘（在SDK-r20上进行测试）
// create dialog
final AlertDialog dialog = ...;
// request keyboard
dialog.getWindow().setSoftInputMode (WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
