In relative layouts, the properties that align to the bottom of the parent layout are android layout

Yes, there are many ways to achieve it, as long as you achieve your effect.

linearlayout, android:orientation="vertical"Isn't that enough?

When you type android when you lay out the border file, you will be prompted when you type android:. The prompt is gone, you delete a few characters, and you will be prompted when you retype android:.

Are you nesting other layouts? Sometimes nesting other layouts automatically masks some methods.

All controls are fine. with the layout weight attribute.

Because there is sunlight outside, the temperature is higher than in the house.

This needs to be done via HTML**. Use the HTML of the web page to disable the zoom in and out of the mobile page. Here's how:

html prohibits mobile pages from zooming in and out**:

This can also be done through the settings of a specific mobile browser.

People say that the relative layout is the weight is a linear layout, well, the relative layout is not written dead and adaptive, it can't be evenly divided.

The two buttons have a linearlayout wrapper, set orientation to horizontal, and then set layout weight=1 and layout width=0 to the two buttons.

Set the weight=1 of these 2 buttons, and write android:layout weight= in the xml"1"

Set two control properties, android:layout weight="1"Indicates that the screen is divided into 2 parts, with each control accounting for 1

You can go to the Android session in Google Io

Or Android's documentation.

However, it can be summarized into the following three points:

1.The relativelayout layout is a bit more flexible.

2.When implementing complex layouts, it may be possible that the performance will be better because of the fewer nesting layers required by relativelayout. However, you should test the mask according to the actual situation, and the subjective judgment is not accurate, please refer to the third point below.

3.For simple layouts, or when there aren't many layers of nested layouts using linearlayout. It is still recommended to use linearlayout for implementation.

Changed to linearlayout layout with higher performance, why? Because the relativelayout layout needs to be evaluated at least twice.
