Question

代码正在运行并打印出“解除键盘”，但键盘不会消失。视图v只是背景视图，按钮和文本字段位于相对布局的顶部。我正在运行S3 API 18

public View v;
public EditText et;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    this.v = (View) findViewById(R.id.backgroundView);
    this.et = (EditText) findViewById(R.id.searchBox);
    Button testButton = (Button) findViewById(R.id.testButton);
    testButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            System.out.println("dismissing keyboard");
            InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
            imm.hideSoftInputFromInputMethod(getWindow().getCurrentFocus().getWindowToken() ,0);
        }
    });
    this.v.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            System.out.println("dismissing keyboard");
            //getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);
            InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);

            imm.hideSoftInputFromInputMethod(getWindow().getCurrentFocus().getWindowToken() ,0);
        }
    });

}

Answer 1

您传递的视图应该是edittext。

public static void hideKeyboard(Context context, View layoutThatContainsEditText) {
    ((InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE))
        .hideSoftInputFromWindow(layoutThatContainsEditText.getApplicationWindowToken(), 0);
  }

Answer 2

变化

getWindow().getCurrentFocus().getWindowToken()

到

et.getApplicationWindowToken()

键盘解雇不适用于Android
