Android 点击按钮弹出输入框和选择框
参考
1、输入框：
final EditText inputServer = new EditText(this);
inputServer.setFilters(new InputFilter[]{new InputFilter.LengthFilter(50)});
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle(“个性点的签名”).setIcon(android.R.drawable.ic_dialog_info).setView(inputServer)
.setNegativeButton(“取消”, null);
builder.setPositiveButton(“确定”, new DialogInterface.OnClickListener() {undefined
public void onClick(DialogInterface dialog, int which) {undefined
String _sign = inputServer.getText().toString();
if(_sign!=null && !_sign.isEmpty())
{undefined
signature_txt.setText(_sign);
}
else
{undefined
Toast.makeText(MemberActivity.this,“签名为空”,Toast.LENGTH_SHORT).show();
}
}
});
builder.show();
2、选择弹出框
final String[] items = {“保密”,“男”,“女”};
new AlertDialog.Builder(MemberActivity.this)
.setTitle(“请选择”)
.setItems(items, new DialogInterface.OnClickListener() {undefined
public void onClick(DialogInterface dialog,
int which) {undefined
TextView item_value = (TextView)memberInfo_tab_list_2.getChildAt(2).findViewById(R.id.item_value);
item_value.setText(items[which]);
}
}).show();
