Android webview scaling and line feed

1. webview supports page scaling. Generally, the following settings can meet the 80% requirement.

// Zoom Switch

Webview. getsettings (). setsuppzoom zoom (true );

Setting this attribute only supports double-click scaling and does not support touch Scaling (this is true in android4.0 and has not been tried on other platforms)

// Set whether to zoom
Webview. getsettings (). setbuiltinzoomcontrols (true );

If this attribute is set, webview. getsettings (). setsuppzoom zoom (true) is also set to true by default.

2. Unlimited Scaling

Unlimited scaling, you need to use the large view mode, as shown below:

// Unlimited Scaling
Webview. getsettings (). setusewideviewport (true); this attribute can be scaled in any proportion.

Note: 1. The initial scaling value can be set as follows: webview. setinitialscale (initalvalue );

2. After zooming, to adapt the content to the screen, do not go beyond the screen display, implement line feed. In this regard, the effect should be controlled by HTML rather than webview. For example, <P style = "word-break: Break-all"> test </P> Enables automatic line feed.
