【中文标题】Android Edittext Drawable 点击卡住焦点【英文标题】:Android Edittext Drawable click stuck focus 【发布时间】:2017-12-23 10:12:27 【问题描述】:我在一个布局上有三个编辑文本。当它为空时,我删除正确的可绘制对象。当它不为空时,我添加了可绘制对象。当您单击可绘制时,我会清除编辑文本。
当我点击 rightdrawable 时,光标卡住了,下划线保持颜色。我很少有 2-3 光标。为什么??我做错了什么?

好的:
布局:
<EditText
android:id="@+id/et1"
android:layout_
android:layout_
android:drawableRight="@mipmap/ic_launcher"/>
<EditText
android:id="@+id/et2"
android:layout_
android:layout_
android:drawableRight="@mipmap/ic_launcher"/>
<EditText
android:id="@+id/et3"
android:layout_
android:layout_
android:drawableRight="@mipmap/ic_launcher"/>
MainActivity 公共类 MainActivity 扩展 AppCompatActivity
private DrawableState etstate1;
private DrawableState etstate2;
private DrawableState etstate3;
private EditText et2;
private EditText et1;
private EditText et3;
@Override
protected void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
et1 = (EditText)findViewById(R.id.et1);
et2 = (EditText)findViewById(R.id.et2);
et3 = (EditText)findViewById(R.id.et3);
etstate1 = new DrawableState(et1);
etstate2 = new DrawableState(et2);
etstate3 = new DrawableState(et3);
et1.setOnTouchListener(new View.OnTouchListener()
@Override
public boolean onTouch(View view, MotionEvent motionEvent)
if (DrawableClick.isDrawableClick(motionEvent, et1, DRAWABLE_RIGHT))
et1.setText("");
etstate1.refreshDrawable();
return true;
return false;
);
et2.setOnTouchListener(new View.OnTouchListener()
@Override
public boolean onTouch(View view, MotionEvent motionEvent)
if (DrawableClick.isDrawableClick(motionEvent, et2, DRAWABLE_RIGHT))
et2.setText("");
etstate2.refreshDrawable();
return true;
return false;
);
et3.setOnTouchListener(new View.OnTouchListener()
@Override
public boolean onTouch(View view, MotionEvent motionEvent)
if (DrawableClick.isDrawableClick(motionEvent, et3, DRAWABLE_RIGHT))
et3.setText("");
etstate3.refreshDrawable();
return true;
return false;
);
et1.addTextChangedListener(new TextWatcher()
@Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2)
@Override
public void onTextChanged(CharSequence charSequence, int i, int i1, int i2)
@Override
public void afterTextChanged(Editable editable)
etstate1.refreshDrawable();
);
et2.addTextChangedListener(new TextWatcher()
@Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2)
@Override
public void onTextChanged(CharSequence charSequence, int i, int i1, int i2)
@Override
public void afterTextChanged(Editable editable)
etstate2.refreshDrawable();
);
et3.addTextChangedListener(new TextWatcher()
@Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2)
@Override
public void onTextChanged(CharSequence charSequence, int i, int i1, int i2)
@Override
public void afterTextChanged(Editable editable)
etstate3.refreshDrawable();
);
助手类:
public class DrawableClick
public static boolean isDrawableClick(MotionEvent event, EditText editText, DrawablePositions drawablePosition)
if (event.getAction() == MotionEvent.ACTION_UP)
if (editText.getCompoundDrawables()[drawablePosition.position] != null && event.getX() >= (editText.getRight() - editText.getLeft() - editText.getCompoundDrawables()[drawablePosition.position].getBounds().width()))
return true;
return false;
public enum DrawablePositions
DRAWABLE_LEFT(0),
DRAWABLE_TOP(1),
DRAWABLE_RIGHT(2),
DRAWABLE_BOTTOM(3);
private int position;
DrawablePositions(int pos)
this.position = pos;
下一步:
公共类 DrawableState
private EditText editText;
private Drawable[] editTextDrawables;
public DrawableState(EditText editText)
this.editText = editText;
saveDrawableState();
refreshDrawable();
public void saveDrawableState()
this.editTextDrawables = editText.getCompoundDrawables();
public void refreshDrawable()
if (editText.getText().toString().equals(""))
editText.setCompoundDrawables(null, null, null, null);
editText.clearFocus();
else
if (editTextDrawables != null)
editText.setCompoundDrawables(editTextDrawables[0], editTextDrawables[1], editTextDrawables[2], editTextDrawables[3]);
【问题讨论】:
【参考方案1】:我找到了解决办法。
改变它
if (DrawableClick.isDrawableClick(motionEvent, et3, DRAWABLE_RIGHT))
...
return true;
return false;
收件人:
if (DrawableClick.isDrawableClick(motionEvent, et3, DRAWABLE_RIGHT))
...
motionEvent.setAction(MotionEvent.ACTION_CANCEL);
return false;
