Question

我有一个从MultiAutoCompleteTextView扩展的自定义视图，以创建像gmail中的联系人一样的chiped视图。当我接触到这个视图并且keyborad被解雇时，casuse堆栈溢出。它只发生在我的nexus 4中这是logcat。

java.lang.StackOverflowError

            at com.tokenautocomplete.TokenCompleteTextView$TokenImageSpan.getSize(TokenCompleteTextView.java:885)

这是我的预备视图代码

private void prepView() {
        int widthSpec = MeasureSpec.makeMeasureSpec((int)maxTextWidth(), MeasureSpec.AT_MOST);
        int heightSpec = MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED);

        view.measure(widthSpec, heightSpec);
        view.layout(0, 0, view.getMeasuredWidth(), view.getMeasuredHeight());
    }

这是tokenCompleteTextView的第260行

private float maxTextWidth() {
    return getWidth() - getPaddingLeft() - getPaddingRight();
}

使用TokenAutoComplete libray作为令牌视图。

这是我的布局

注意

我知道如何解雇键盘。那不是我的问题。当我在特定视图中执行此操作时，出现stackoverflow错误。

Answer 1

1。）试试这个，希望它能解决你的问题，我使用下面的代码来隐藏软件键盘

public void hideSoftKeyboard(Activity activity) {
    InputMethodManager inputMethodManager = (InputMethodManager) activity
            .getSystemService(Activity.INPUT_METHOD_SERVICE);
    inputMethodManager.hideSoftInputFromWindow(activity.getCurrentFocus()
            .getWindowToken(), 0);
}

OR

如果我需要关心键盘出现和消失的时间（经常是这样），那么我所做的就是将我的顶级布局类自定义为覆盖onMeasure（）的类。基本逻辑是，如果布局发现自己填充的内容明显少于窗口的总面积，则可能会显示软键盘。

  import android.app.Activity;
  import android.content.Context;
  import android.graphics.Rect;
  import android.util.AttributeSet;
  import android.widget.LinearLayout;

/ * * LinearLayoutThatDetectsSoftKeyboard - LinearLayout的一种变体，可以检测何时 *软键盘显示和隐藏（Android无法告诉你，奇怪的是）。 * /

public class LinearLayoutThatDetectsSoftKeyboard extends LinearLayout {

public LinearLayoutThatDetectsSoftKeyboard(Context context, AttributeSet attrs) {
    super(context, attrs);
}

public interface Listener {
    public void onSoftKeyboardShown(boolean isShowing);
}
private Listener listener;
public void setListener(Listener listener) {
    this.listener = listener;
}

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    int height = MeasureSpec.getSize(heightMeasureSpec);
    Activity activity = (Activity)getContext();
    Rect rect = new Rect();
    activity.getWindow().getDecorView().getWindowVisibleDisplayFrame(rect);
    int statusBarHeight = rect.top;
    int screenHeight = activity.getWindowManager().getDefaultDisplay().getHeight();
    int diff = (screenHeight - statusBarHeight) - height;
    if (listener != null) {
        listener.onSoftKeyboardShown(diff>128); // assume all soft keyboards are at least 128 pixels high
    }
    super.onMeasure(widthMeasureSpec, heightMeasureSpec);       
}

}

然后在你的Activity类......

 public class MyActivity extends Activity implements      LinearLayoutThatDetectsSoftKeyboard.Listener {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    ...
    LinearLayoutThatDetectsSoftKeyboard mainLayout = (LinearLayoutThatDetectsSoftKeyboard)findViewById(R.id.main);
    mainLayout.setListener(this);
    ...
}


@Override
public void onSoftKeyboardShown(boolean isShowing) {
    // do whatever you need to do here
}

 ...
}

Answer 2

我使用此代码隐藏软键盘

//关闭软键盘

InputMethodManager inputMethod = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
inputMethod.hideSoftInputFromWindow(getView().getWindowToken(), 0);

Answer 3

我遇到了同样的问题。我不知道为什么会这样。我在不同的设备和模拟器中测试过。这个错误只发生在某些设备上，而在模拟器中我无法模拟它。这就是我所做的：

@Override
public int getSize(Paint paint, CharSequence charSequence, int i, int i2, Paint.FontMetricsInt fm) {
        try{
            prepView();
        }catch(StackOverflowError error){

        }
        ...

此代码阻止应用程序关闭。
