在执行 Layout Inflater 时，TextView 中的文本没有改变

发布于 2024-12-16 02:48:04 字数 499 浏览 3 评论 0原文

在我的应用程序中，当加载活动时，我正在执行以下操作

setContentView(R.layout.main2);
layoutToAdd = (LinearLayout) findViewById(R.id.linearLayout1);

for(i=0; i<num;i++)
{
    LayoutInflater inflater = LayoutInflater.from(getApplicationContext());
    View view = inflater.inflate(R.layout.camera, null);
    layoutToAdd.addView(view);
}

num 的值每次都不同。

在我的 LayoutInflater 布局中，我有一个文本视图、编辑文本和一个按钮。

现在它们根据 num 中提到的次数显示，现在每次我想要更改文本和按钮名称。如何设置TextView和Button的文本。

in my app when the activity get loaded, i am doing the following

setContentView(R.layout.main2);
layoutToAdd = (LinearLayout) findViewById(R.id.linearLayout1);

for(i=0; i<num;i++)
{
    LayoutInflater inflater = LayoutInflater.from(getApplicationContext());
    View view = inflater.inflate(R.layout.camera, null);
    layoutToAdd.addView(view);
}

The value of num differs for each time.

In my LayoutInflater layout i have a text view, edit text and a button.

Now they are shown according to the number of times mentioned in num, now for each time i want the text and button name to be changed. How to set the text for TextView and Button.

只需在膨胀布局后设置它们即可

View view = inflater.inflate(R.layout.camera, null);
TextView tv = view.findViewById(R.id.textviewid); //id defined in camera.xml
Button b = view.findViewById(R.id.buttonid);      //id defined in camera.xml
tv.setText();
b.setText();
layoutToAdd.addView(view);

Just set them after you inflate the layout

View view = inflater.inflate(R.layout.camera, null);
TextView tv = view.findViewById(R.id.textviewid); //id defined in camera.xml
Button b = view.findViewById(R.id.buttonid);      //id defined in camera.xml
tv.setText();
b.setText();
layoutToAdd.addView(view);

我的建议是，您应该创建一个仅包含 LinearLayout 的 xml 文件。

然后编程，您应该创建 TextViews、EditTexts 和 Buttons 并将其添加到 LinearLayout。

您可以设置这些组件的不同属性，如下所示：

这是设置 TextView 属性的示例。对于其余组件，您可以设置相同的属性。

TextView tv=new TextView(context);
tv.setBackgroundResource(R.drawable.textview_bg);
tv.setPadding(20, 5, 40, 5);
tv.setText("set your text");
tv.setLayoutParams(new Gallery.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
tv.setTextColor(Color.RED);
tv.setClickable(true);
tv.setId(id);//where id is an integer which should be unique for each TextView

layout.addView(tv);

此外，您还需要在 for 循环内创建并添加所有这三个组件，根据您用于迭代循环的 i 提供唯一的 id！并且您可以为文本视图和按钮设置一个字符串数组，以在 for 循环中设置它们的名称，这将您可以更轻松地在循环中传递您想要设置的字符串。

What I suggest it,you should create an xml file containing just a LinearLayout.

Then programaticall,you should create TextViews,EditTexts and Buttons and add it to LinearLayout.

You can set different properties of those components like below:

Here is example of setting TextView's properties.For rest of the components,you can set the same.

TextView tv=new TextView(context);
tv.setBackgroundResource(R.drawable.textview_bg);
tv.setPadding(20, 5, 40, 5);
tv.setText("set your text");
tv.setLayoutParams(new Gallery.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
tv.setTextColor(Color.RED);
tv.setClickable(true);
tv.setId(id);//where id is an integer which should be unique for each TextView

layout.addView(tv);

Also you need to create and add all these three component inside the for loop,providing unique ids depending on i you use to iterate the loop!And you can have a String array for textviews and buttons to set their names in for loop,which would be easier for you for passing the string you like to set to them in loop.
