当用户在软键盘上按“完成”时,键盘关闭.我想要它,只有在一定条件为真时才会关闭(例如,密码输入正确).
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,这不行的原因可能是因为它运行这个代码之前,它实际上关闭了自己的软键盘,但这就是为什么我需要帮助.我不知道另一种方式.
activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
那种事情,但我不知道肯定.
解:
EditText et = (EditText)findViewById(R.id.et); et.setonEditorActionListener(new OnEditorActionListener() { @Override public boolean onEditorAction(TextView v,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,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 } });
解决方法
