Android 如何通过单击imagebutton设置edittext可动态编辑?
我使用for循环将ArrayList中的字符串值动态列出到EditText中,每个EditText旁边都有ImageButtons。我想要这样:当我点击一个ImageButton时,相应的EditText是可编辑的。 以下是我的活动代码:Android 如何通过单击imagebutton设置edittext可动态编辑?,android,android-layout,android-edittext,android-linearlayout,Android,Android Layout,Android Edittext,Android Linearlayout,我使用for循环将ArrayList中的字符串值动态列出到EditText中,每个EditText旁边都有ImageButtons。我想要这样:当我点击一个ImageButton时,相应的EditText是可编辑的。 以下是我的活动代码: LinearLayout container = (LinearLayout) findViewById(R.id.container); LayoutInflater layoutInflater = (LayoutInflater) getBaseCont
LinearLayout container = (LinearLayout) findViewById(R.id.container);
LayoutInflater layoutInflater = (LayoutInflater) getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
final View showProduct = layoutInflater.inflate(R.layout.row_show_product, null);
for (int i = 0; i < product.size(); ++i) {
final EditText edt_row_show_product = (EditText) showProduct.findViewById(R.id.edt_row_show_product);
edt_row_show_product.setText(product.get(i));
ImageButton ib_row_show_product_edit_icon = (ImageButton)showProduct.findViewById(R.id.ib_row_show_product_edit_icon);
ib_row_show_product_edit_icon.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//container.getParent()...;
}
});
container.addView(showProduct);
}
LinearLayout container=(LinearLayout)findViewById(R.id.container);
LayoutInflater LayoutInflater=(LayoutInflater)getBaseContext().getSystemService(Context.LAYOUT\u INFLATER\u SERVICE);
最终视图showProduct=layoutInflater.flate(R.layout.row\u show\u product,null);
对于(int i=0;i
您可以使用相应的编辑文本设置imageview的标记,并在单击onClick
final EditText edt_row_show_product = (EditText) showProduct.findViewById(R.id.edt_row_show_product);
edt_row_show_product.setText(product.get(i));
ImageButton ib_row_show_product_edit_icon =(ImageButton)showProduct.findViewById(R.id.ib_row_show_product_edit_icon);
ib_row_show_product_edit_icon.setTag(edt_row_show_product); //set the Edittext object here above
ib_row_show_product_edit_icon.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
EditText et = (EditText)v.getTag()
//do what ever you want with the EditText
}
});
我制作了一个快速应用程序来满足您的需求。请看一看 我让代码在一个片段中工作,因此如果您在活动中工作,请进行必要的更改 片段代码:

代码可能有点粗糙的边缘,因为它是真正的快速。请做相关修改。希望这有帮助!:) 制作图像按钮和编辑文本的ID数组。然后做你已经做过的事情。@andris11m另一种方法是创建和排列列表并添加edittext,同时将edittext的索引设置为imageview的标记,如上所述。
