标签: android searchview
1 首先在水平布局中创建编辑文本和图像视图。
2 使图像视图可见为假。会有2张图片true_image和false_image,根据编辑文本值改变图片查看图片。
3 编辑文本的方法如下:
edittext.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
// TODO Auto-generated method stub
Value = edittext.getText().toString();
if(Your Condition){
imageview.setimage(R.Drawable.true_image);
}else{
imageview.setimage(R.Drawable.false_image);
}
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
// TODO Auto-generated method stub
}
@Override
public void afterTextChanged(Editable s) {
// TODO Auto-generated method stub
}
});
}
希望这个答案对你有所帮助。

您可以使用此代码自定义默认搜索视图
@Override
public boolean onCreateOptionsMenu(final Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.xyz, menu);
MenuItem searchItem = menu.findItem(R.id.action_search);
if (searchItem != null) {
SearchView searchView = (SearchView) searchItem.getActionView();
if (searchView != null) {
// Full view of search
View searchPlate = searchView.findViewById(android.support.v7.appcompat.R.id.search_plate);
// Apply customisation as you want
ImageView searchClose =(ImageView) searchView.findViewById(android.support.v7.appcompat.R.id.search_close_btn);
// Edittext of search view so you can customize this also
EditText searchSourceText = (EditText) searchView.findViewById(android.support.v7.appcompat.R.id.search_src_text);
}
}
}

改变下划线颜色:
View searchplate =searchView.findViewById(android.support.v7.appcompat.R.id.search_plate);
searchplate.getBackground().setColorFilter(Color.BLUE, PorterDuff.Mode.MULTIPLY);
