Question

在我的Android应用程序中有一个竞赛模块，其中将显示一个问题及其选项。工作正常但是当我们添加长问题时它不会显示全文。我正在使用对话框，我的dialogbox.xml看起来像

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

        <RadioButton

    </RadioGroup>

    <LinearLayout

            android:layout_centerHorizontal="true"
            android:text="Close" />
    </LinearLayout>

</RelativeLayout>

我的activity.java我写得像

final Dialog dialog = new Dialog(HelloFMActivity.this);
dialog.setContentView(R.layout.dialogbox);
dialog.setTitle("my long question bla bla bla bla bla bla bla");

Answer 1

在问题的布局中添加另一个TextView。避免将问题设置为对话框的标题。

Answer 2

您可以看到此链接

http://androidexample.com/Custom_Dialog_-_Android_Example/index.php?view=article_discription&aid=88&aaid=111

作为您的代码

final Dialog dialog = new Dialog(MainActivity.this);

                    //setting custom layout to dialog
                dialog.setContentView(R.layout.cusotm_dialog_layout);
                dialog.setTitle("Custom Dialog");

Answer 3

另一招技巧

按程序方式创建 TextView

TextView TvTitle = new TextView(YourclassName.this); TvTitle.setText("Alert"); TvTitle.setGravity(Gravity.CENTER); TvTitle.setTextSize(30); TvTitle.setTextColor(Color.WHITE); Dialog_Object.setCustomTitle(TvTitle);

或

自定义对话框布局 像

Dialog custom_connection_dialog = new Dialog(this,android.R.style.Theme_Holo_Light_Dialog_MinWidth); custom_connection_dialog.getWindow().setBackgroundDrawable(new ColorDrawable((0xff000000))); custom_connection_dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); custom_connection_dialog.setCancelable(true); custom_connection_dialog.setContentView(R.layout.your_layout); custom_connection_dialog.getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, Color.parseColor("#FFFFFF")); Button TurnAgain = (Button) custom_connection_dialog.findViewById(R.id.ButtonID); TurnAgain.setOnClickListener(this); custom_connection_dialog.show();

编辑

LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT)); params.setMargins(,,,); tv1.setLayoutParams(params);

Answer 4

使用此

AlertDialog.Builder alertDialog = new AlertDialog.Builder(HelloFMActivity.this);
alertDialog.setTitle("your title");
alertDialog.setMessage("my long question bla bla bla bla bla bla bla");

而不是

dialog.setTitle("my long question bla bla bla bla bla bla bla");

Android对话框标题高度
