我为AlertDialog框创建了自定义标题。但我无法集中信息。它总是左对齐。
TextView vehicle_no = (TextView) findViewById(R.id.vehicle_no);
String ScoreTitle = getResources().getString(R.string.AlertTitle);
AlertDialog.Builder alrtbuilder = new AlertDialog.Builder(this);
Context mContext = alrtbuilder.getContext();
LayoutInflater mLayoutInflater = LayoutInflater.from(mContext);
View mView = mLayoutInflater.inflate(R.layout.simple_dialog, null);
TextView mTextView = (TextView) mView.findViewById(R.id.title_text);
mTextView.setText(ScoreTitle);
AlertDialog框有正面和负面按钮
alrtbuilder.setCustomTitle(mView);
alrtbuilder.setMessage(vehicle_no.getText().toString().toUpperCase()+" "+"?")
.setPositiveButton(R.string.ok, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
insert_timecard();
}
})
.setNegativeButton(R.string.cancel, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
dialogInterface.dismiss();
}
}).show;

在您的布局android:gravity="center"
中将TextView
添加到标识为R.id.title_text
的{{1}}。
R.layout.simple_dialog
要将默认消息 <TextView
android:id="@+id/title_text"
android:layout_width="match_parent"
android:gravity="center"
android:layout_height="wrap_content" />
置于中心位置,您必须在TextView
之后从对话框中获取TextView
。
show()
我不知道它是否是一个好的方法,但您也可以将自定义视图设置为整个对话框,然后可以轻松处理事情。

添加:
mTextView.setGravity(Gravity.CENTER_HORIZONTAL);
TextView vehicle_no = (TextView) findViewById(R.id.vehicle_no); String ScoreTitle = getResources().getString(R.string.AlertTitle); AlertDialog.Builder alrtbuilder = new AlertDialog.Builder(this); Context mContext = alrtbuilder.getContext(); LayoutInflater mLayoutInflater = LayoutInflater.from(mContext); View mView = mLayoutInflater.inflate(R.layout.simple_dialog, null); TextView mTextView = (TextView) mView.findViewById(R.id.title_text); mTextView.setGravity(Gravity.CENTER_HORIZONTAL); mTextView.setText(ScoreTitle);
这应解决:

如何添加此内容?
TextView messageView = (TextView)dialog.findViewById(android.R.id.message);
messageView.setGravity(Gravity.CENTER);
