有两种方法1)以编程方式2)使用xml布局
1)=======>
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setView(layout);
builder.setTitle("Title");
alertDialog = builder.create();
alertDialog.show();
alertDialog.getWindow().setLayout(600, 400); //Controlling width and height.
( or )
alertDialog.show();
WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
lp.copyFrom(alertDialog.getWindow().getAttributes());
lp.width = 150;
lp.height = 500;
lp.x=-170;
lp.y=100;
alertDialog.getWindow().setAttributes(lp);
如果要显示要显示的布局,请Alert dialog
参见this
2)========>
choose.xml
<TextView
android:id="@+id/img"
android:layout_width="wrap_content"
android:text="@string/choose"
android:textSize="25dp"
android:textColor="#fff"
android:layout_height="50dp"/>
<TableLayout android:id="@+id/table"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#fff"
android:orientation="vertical">
<TableRow
android:id="@+id/tr1"
android:orientation="horizontal"
android:layout_margin="10dp">
<ImageView
android:contentDescription="@string/phone"
android:src="@drawable/phone"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<TextView
android:id="@+id/phnText"
android:layout_width="wrap_content"
android:text="@string/phone"
android:gravity="left|center_vertical"
android:layout_marginLeft="10dp"
android:textSize="25dp"
android:textColor="#000"
android:layout_height="50dp"/>
</TableRow>
<View
android:layout_width="fill_parent"
android:layout_height="1dip"
android:background="#FF000000" />
<TableRow
android:id="@+id/tr2"
android:orientation="horizontal"
android:layout_margin="10dp">
<ImageView
android:contentDescription="@string/sms"
android:src="@drawable/sms"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<TextView
android:id="@+id/smsText"
android:layout_width="wrap_content"
android:text="@string/sms"
android:gravity="left|center_vertical"
android:layout_marginLeft="10dp"
android:textSize="25dp"
android:textColor="#000"
android:layout_height="50dp"/>
</TableRow>
</TableLayout>
</LinearLayout>
将其显示为弹出窗口,如下所示
private void showPopUp()
{
final AlertDialog.Builder helpBuilder = new AlertDialog.Builder(this);
helpBuilder.setTitle("");
LayoutInflater inflater = getLayoutInflater();
final View checkboxLayout = inflater.inflate(R.layout.choose, null);
helpBuilder.setView(checkboxLayout);
final AlertDialog helpDialog = helpBuilder.create();
helpDialog.show();
TableRow tablerowPhone = (TableRow)checkboxLayout.findViewById(R.id.tr1);
TableRow tablerowSms = (TableRow)checkboxLayout.findViewById(R.id.tr2);
tablerowPhone.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
helpDialog.dismiss();
Uri callUri = Uri.parse("tel:" + listview_array[4]);
Intent intent = new Intent(Intent.ACTION_CALL, callUri);
startActivity(intent);
}
});
tablerowSms.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
helpDialog.dismiss();
Uri smsUri = Uri.parse("sms:" + listview_array[4]);
Intent intent = new Intent(Intent.ACTION_VIEW, smsUri);
startActivity(intent);
}
});
}
在您想要的地方调用此showPopUp()
方法。这样您就可以在xml文件中为布局设置高度和宽度

试试这个,这对我有用,
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setView(layout);
builder.setTitle("Title");
alertDialog = builder.create();
alertDialog.getWindow().setLayout(600, 400); //Controlling width and height.
alertDialog.show();
