推荐答案

确保onCreateInputConnection覆盖方法中的输入连接不为空。

Make sure the input connection is not null in your onCreateInputConnection override method.

@Override
public InputConnection onCreateInputConnection(EditorInfo outAttrs) {
    InputConnection inputConnection = super.onCreateInputConnection(outAttrs);
    if (inputConnection == null)
    {
        return null;
    }
    return new MyInputConnectionWrapper(inputConnection,
            true);
}

其中MyInputConnectionWrapper是从InputConnectionWrapper扩展的自定义输入连接包装。

Where MyInputConnectionWrapper is your custom input connection wrapper which is extended from InputConnectionWrapper.
