简述:
Android EditText常见的一写处理方法汇总,这里会不断更新。
EditView默认不显示软键盘
方案一:在 AndroidMainfest.xml中选择哪个activity,设置windowSoftInputMode属性为 adjustUnspecified|stateHidden:
<activity
android:name=".trace.view.SupplementReceiptActivity"
android:exported="false"
android:windowSoftInputMode="adjustUnspecified|stateHidden" />
这种方案只是让键盘不显示,并不能让Edittext失去焦点。
方案二:让 EditText失去焦点,使用EditText的clearFocus方法
EditText edit=(EditText)findViewById(R.id.edit);
edit.clearFocus();
EditText设置DrawableRight和DrawableLeft 点击事件
在开发中经常会遇到这样的情况:点击搜索图标开始搜索输入框内容,OK,那就得重写EditText的onTouch()方法:
public class YCEditText extends EditText {
private DrawableLeftListener mLeftListener;
private DrawableRightListener mRightListener;
final int DRAWABLE_LEFT = 0;
final int DRAWABLE_TOP = 1;
final int DRAWABLE_RIGHT = 2;
final int DRAWABLE_BOTTOM = 3;
public YCEditText(Context context, AttributeSet attrs) {
super(context, attrs);
}
public YCEditText(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
public YCEditText(Context context) {
super(context);
}
public void setDrawableLeftListener(DrawableLeftListener listener) {
this.mLeftListener = listener;
}
public void setDrawableRightListener(DrawableRightListener listener) {
this.mRightListener = listener;
}
public interface DrawableLeftListener {
public void onDrawableLeftClick(View view);
}
public interface DrawableRightListener {
public void onDrawableRightClick(View view);
}
@Override
public boolean onTouchEvent(MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_UP:
if (mRightListener != null) {
Drawable drawableRight = getCompoundDrawables()[DRAWABLE_RIGHT];
if (drawableRight != null && event.getRawX() >= (getRight() - drawableRight.getBounds().width())) {
mRightListener.onDrawableRightClick(this);
return true;
}
}
if (mLeftListener != null) {
Drawable drawableLeft = getCompoundDrawables()[DRAWABLE_LEFT];
if (drawableLeft != null && event.getRawX() <= (getLeft() + drawableLeft.getBounds().width())) {
mLeftListener.onDrawableLeftClick(this);
return true;
}
}
break;
}
return super.onTouchEvent(event);
}
}
使用就像一个button一样,如下:
ycEditText = (YCEditText) findViewById(R.id.xedit);
ycEditText.setDrawableLeftListener(new YCEditText.DrawableLeftListener() {
@Override
public void onDrawableLeftClick(View view) {
Toast.makeText(MainActivity.this, XView.getText().toString(), Toast.LENGTH_SHORT).show();
}
});
