Question

不能比标题中说清楚得多。我有一个由文本输入布局包装的EditText。当EditText失去焦点时，我试图触发一个事件。但是，一旦应用了事件侦听器，TextInputLayout就不再为文本设置动画，它只是位于editText行，直到输入信息为止，此时它会进行动画处理。任何人都可以给我一些见解，为什么会发生这种情况？

编辑：布局文件。

Answer 1

这并没有解决问题，但确实提供了一些见解（如果我找到解决方案，我会更新），但似乎动画提示依赖于OnFocusChangedListener，它会被覆盖当你添加自己的监听器。

我们现在正在使用不同的方式来确定EditText是否有针对性。现在做类似的事情：

TextInputLayout inputLayout = ...; EditText editText = inputLayout.getEditText(); final OnFocusChangeListener existing = editText.getOnFocusChangeListener(); editText.setOnFocusChangeListener(new OnFocusChangeListener() { public void onFocusChange(View view, boolean focused) { existing.onFocusChange(view, focused); // Your custom logic } });

Answer 2

我不得不处理同样的问题。

我使用的解决方法是使用自定义EditText并在触发onFocusChanged方法时为其调用自定义侦听器。

自定义EditText （未显示Boiler plate代码）

public class EditTextPlus extends AppCompatEditText {
    //This is the custom listener you will use
    public OnFocusChangeListener customListener;

    @Override
    protected void onFocusChanged(boolean focused, int direction, Rect previouslyFocusedRect) {
        super.onFocusChanged(focused, direction, previouslyFocusedRect);
        if (customListener != null) {
            customListener.onFocusChange(this, focused);
        }
    }
}

在活动/片段中

yourEditText.customListener = new View.OnFocusChangeListener() {
    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        //Do your stuff
    }
}

不要忘记在xml中使用自定义EditText，而不是默认的EditText。

当OnFocusChangeListener应用于包装的EditText时，TextInputLayout不动画
