Android输入法切换引导功能

在安装百度、搜狗输入法之后，会引导我们设置为当前的输入法，记下一下几个接口：

第一步：调出输入法设置界面

open.setOnClickListener(new OnClickListener(){

			@Override
			public void onClick(View v) {
				try {
					Intent intent = new Intent();
					intent.setAction("android.intent.action.MAIN");
					intent.setComponent(new ComponentName(
							"com.android.settings",
							"com.android.settings.LanguageSettings"));
					startActivityForResult(intent, 0);
				} catch (Exception e) {
					try {
						Intent intent2 = new Intent();
						intent2.setAction("android.settings.INPUT_METHOD_SETTINGS");
						startActivity(intent2);
					} catch (Exception ex) {
						Toast.makeText(Setting.this, "无法打开，请进入系统界面手动设置！", Toast.LENGTH_LONG).show();
						ex.printStackTrace();
					}
					e.printStackTrace();
				}
			}

		});

第二步：调出输入法切换对话框

select.setOnClickListener(new OnClickListener(){

			@Override
			public void onClick(View v) {
				try {
					((InputMethodManager) Setting.this.getApplicationContext()
							.getSystemService("input_method"))
							.showInputMethodPicker();
				} catch (Exception e) {
					Toast.makeText(Setting.this, "无法打开，请进入系统界面手动设置！",
							Toast.LENGTH_LONG).show();
					e.printStackTrace();
				}
			}
			
		});
