Android 在警报对话框中显示文本视图
在我的代码中,我有一个Android 在警报对话框中显示文本视图,android,textview,android-alertdialog,Android,Textview,Android Alertdialog,在我的代码中,我有一个警报对话框和一个文本视图。我想在我的AlertDialog中显示这个TextView,但我不知道怎么做。我不知道如何在警报对话框中添加视图 我可以显示我的代码,但我认为它没有用 谢谢 编辑: 谢谢你的回答。我刚做了一个测试,效果非常好 这是我的工作代码: package com.example.testalertdialog; import android.app.Activity; import android.app.AlertDialog; import andro

和一个文本视图
。我想在我的AlertDialog
中显示这个TextView
,但我不知道怎么做。我不知道如何在警报对话框

谢谢你的回答。我刚做了一个测试,效果非常好
这是我的工作代码:
package com.example.testalertdialog;
import android.app.Activity;
import android.app.AlertDialog;
import android.os.Bundle;
import android.widget.LinearLayout;
import android.widget.TextView;
public class MainActivity extends Activity {
LinearLayout layout;
AlertDialog ad;
TextView tv1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
layout = new LinearLayout(this);
ad = new AlertDialog.Builder(this).create();
tv1 = new TextView(this);
setContentView(layout);
tv1.setText("Test");
ad.setView(tv1);
ad.show();
}
}
Edit2:但是为什么这个代码不起作用
package com.example.testalertdialog;
import android.annotation.SuppressLint;
import android.app.Activity;
import android.app.AlertDialog;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.LinearLayout;
import android.widget.TextView;
@SuppressLint("HandlerLeak")
public class MainActivity extends Activity implements OnClickListener{
LinearLayout layout;
AlertDialog ad;
TextView tv1;
Button b1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
layout = new LinearLayout(this);
tv1 = new TextView(this);
b1 = new Button(this);
b1.setOnClickListener(this);
layout.addView(b1);
ad = new AlertDialog.Builder(this).create();
setContentView(layout);
tv1.setText("Test");
}
@Override
public void onClick(View v) {
if (v == b1) {
ad.setMessage("Chargement");
ad.show();
ad.setView(tv1);
}
}
}可以使用
setView
方法将视图添加到AlertDialog
中
例如:
AlertDialog dialog = new AlertDialog.Builder(this).create();
dialog.setView(your_textview);
dialog.show();
试试这个
在这里,您需要设置自己的布局
像这样
final Dialog dialog = new Dialog(context);
dialog.setContentView(R.layout.custom);
它将为您提供textview
内部对话框
试试这个
//文本视图的布局
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#B7B7B8"
android:text="Hello"/>
</LinearLayout>
使用
setView
方法的另一个示例:
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater inflater = getActivity().getLayoutInflater();
builder.setView(inflater.inflate(R.layout.name_dialog, null));
builder.create().show();
请尝试此示例代码片段
Dialog dialog = new Dialog(context);
dialog.setContentView(R.layout.custom);
dialog.setTitle("Title...");
// set the custom dialog components - text, image and button
TextView text = (TextView) dialog.findViewById(R.id.text);
text.setText("Android custom dialog example!");
ImageView image = (ImageView) dialog.findViewById(R.id.image);
image.setImageResource(R.drawable.ic_launcher);
Button dialogButton = (Button) dialog.findViewById(R.id.dialogButtonOK);
// if button is clicked, close the custom dialog
dialogButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
dialog.dismiss();
}
});
dialog.show();
在drawable中创建文件名custom\u window\u dialog\u frame.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle"> <!-- this shape is used as shadow -->
<padding android:bottom="3dp"
android:left="3dp"
android:right="3dp"
android:top="3dp"/>
<solid android:color="#44000000"/>
<!-- <corners android:radius="5dp"/> -->
</shape>
</item>
</layer-list>
自定义对话框将如下图所示。享受编码:)
在零件自定义布局中-您可以为alertDialog创建自定义布局,不仅可以在textview中,还可以在任何地方 为了简化:这是我的游戏代码
//create builder
AlertDialog.Builder builder = new AlertDialog.Builder(GWGPlay.this);
//inflate layout from xml. you must create an xml layout file in res/layout first
LayoutInflater inflater = GWGPlay.this.getLayoutInflater();
View layout = inflater.inflate(R.layout.guesskeyword /*my layout here*/, null);
builder.setView(layout);
//set 2 main buttons
builder.setPositiveButton("Answer", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
endGame(true);
}
});
builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
}
});
builder.show();
简短回答:在show()之后调用setView(),此代码将被忽略/不再处理。您需要最后调用show()
是的,它很有用。显示您的代码。相关snippetsCode正确且显示对话框。此警报中没有可见的文本视图:(@Yoda for EditText使用最终EditText输入=新建EditText(此);
