当用户按下软键盘上的“完成”时,键盘关闭。我希望它只有在特定条件成立时才会关闭(例如,密码输入正确)。
这是我的代码(在按下“完成”按钮时设置监听器):
final EditText et = (EditText)findViewById(R.id.et);
et.setOnEditorActionListener(new OnEditorActionListener()
{
@Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event)
{
if(actionId==EditorInfo.IME_ACTION_DONE)
{
if (et.getText().toString().equals(password)) // they entered correct
{
// log them in
}
else
{
// bring up the keyboard
getWindow().setSoftInputMode(
WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
Toast.makeText(Main.this, "Incorrect.", Toast.LENGTH_SHORT).show();
}
}
return false;
}
});
我意识到这不起作用的原因可能是因为它运行此代码before它实际上会自行关闭软键盘,但这就是我需要帮助的原因。我不知道还有什么办法。
一个可能的答案主题可以是:
activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
诸如此类的事情,但我不确定。
解决方案:
EditText et = (EditText)findViewById(R.id.et);
et.setOnEditorActionListener(new OnEditorActionListener()
{
@Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event)
{
if(actionId==EditorInfo.IME_ACTION_DONE)
{
if (et.getText().toString().equals(password)) // they entered correct
{
// log them in
return false; // close the keyboard
}
else
{
Toast.makeText(Main.this, "Incorrect.", Toast.LENGTH_SHORT).show();
return true; // keep the keyboard up
}
}
// if you don't have the return statements in the if structure above, you
// could put return true; here to always keep the keyboard up when the "DONE"
// action is pressed. But with the return statements above, it doesn't matter
return false; // or return true
}
});
